"Amateur," she said.
   And just like that, the spell was broken. Bad Penny's glamour snapped off, and she was just another really good-looking woman with a bit of a weight problem. She looked at us, open-mouthed, absolutely dumbfounded. I don't think anyone had ever broken her spell that easily, that casually, before. I smiled at her.
   "Nice try, Penny. But I have been there, and done that, and, to be honest, I've known better."
   She stamped one high-heeled foot, said a few baby swear words, and suddenly she had two really big guns in her white-gloved hands. She opened fire at point-blank range, the explosions deafeningly loud, but I was already moving. I knew how she operated. And yet even as I dodged and ducked, it was clear she wasn't just targeting me. We all had to die, so no-one would ever be told about the failure of her glamour. And that... was a mistake. If she'd concentrated on me, she might have got somewhere. I'm fast, and I'm tricky, but I'm not bullet-proof.
   The bullets couldn't even find Madman. He just stood there, blinking owlishly, his mind on other things, while bullets ricocheted from the wall behind him. I wasn't sure what damage bullets could do to a demon succubus, but Sinner didn't wait to find out. He stepped quickly forward, to stand between his love and Bad Penny, and the bullets thudded into his chest over and over again, to no obvious effect. Bad Penny blinked a few times, then shot him in the head. That didn't help, so she kicked his feet out from under him. He crashed onto his back, and Bad Penny targeted Pretty Poison. I grabbed Bad Penny from behind, pinioning her arms, and she bent sharply forward at the waist and threw me right over her head. I hit the ground hard, but kept rolling. Bullets smashed into the ground where I'd been. Sinner was back on his feet and advancing on Bad Penny. She emptied her guns into him, going for all the most vulnerable points, but he didn't even flinch as the bullets punched into him. No blood flowed. Like Cain before him, he bore the mark of his offence on his brow, and nothing of this world could ever really harm him again. He stopped right in front of Bad Penny, and she put her last bullet right through his left eye.
   "Ouch," Sinner said dryly. There was only the slightest of pauses before his eyeball rebuilt itself, then he gargled and spat the bullet out into his palm. He offered it to Bad Penny. "Yours, I believe."
   She snarled prettily, made her guns disappear, and snatched two silver knives out of nowhere. She buried them both up to the hilt in his chest. They were magical weapons, scored with ancient runes, one cursed and one blessed. I'd known gods who would have died from an attack like that. Sinner just stood there and took it. I felt like applauding. Bad Penny folded her arms over her impressive chest and pouted.
   "Now that's just not fair, darling."
   "Step aside, Sidney," said Pretty Poison, at Sinner's shoulder. "I have business with this woman. Very nasty business."
   "No," said Sinner.
   "She tried to kill you, my darling! I can't allow that to go unpunished. It's not in my nature."
   "You came up out of Hell to be with me, in order to change your nature. Remember?"
   "Yes, but..."
   "Hush," said Sinner, and the demon succubus hushed, for the moment.
   Bad Penny poked out her tongue at Pretty Poison, then smiled hopefully at Sinner. "If you're not actually going to kill me, darling, could I please have my knives back? They are family heirlooms, and Daddy would be furious if I lost them."
   Sinner tugged the blades out of his chest with some effort and handed them back in a gentlemanly way. Bad Penny accepted the knives, glanced briefly in my direction to see if she still had a chance of picking me off, decided she hadn't, and made the knives disappear. I came forward to join her.
   "What are we going to do with you, Penny?" I said.
   "We can't just let you go. You'd only carry on following us, looking for another good place to ambush us, with better weapons. You're like me; you never give up on a case."
   "I am nothing like you, John Taylor! I have style."
   Faster than any of us could react, Pretty Poison surged forward, grabbed Bad Penny by the throat and bent her over backwards. Penny squealed and struggled furiously, but couldn't break the succubus's hold. Pretty Poison's fingers now ended in claws, and her widely smiling mouth was packed full of pointed teeth. The red lips were very close to Penny's neck, and she didn't look like an English public school girl any more. She looked like what she was, a demon spat up from Hell.
   "Don't!" said Sinner. He started forward, then stopped abruptly as Pretty Poison set her sharp teeth directly against Penny's throat, the points just dimpling the skin. Sinner raised his hands calmingly. "Please. Don't kill her."
   "She has to die," Pretty Poison said reasonably, her lips brushing Penny's throat. "You heard her, Sidney; she's under orders to kill anyone who might talk to us. Either I rip her throat out, or the case stops here."
   "No case of mine has ever been worth the sacrifice of an innocent life," I said.
   Pretty Poison raised an eyebrow. "You think this is an innocent?"
   "Maybe not technically, but yes. Kill her, and you're my enemy. Forever."
   Pretty Poison grinned. "Never threaten a demon, John Taylor. We have long memories." She looked at Sinner. "Besides, you wouldn't let him hurt me, would you, Sidney?"
   "You're trying to confuse the issue," said Sinner. "All that matters is that you can't kill this woman now that she's helpless. It may be that she deserves it, but we are not like her. We have to be better than that. So let her go. For me."
   Pretty Poison considered this for a long moment, while Bad Penny barely dared breathe, then the demon succubus abruptly dropped her victim to the ground and strolled unhurriedly back to Sinner. Bad Penny rose to her feet, brushed herself down, and gave me a smile that was only just a little shaky.
   "I knew you wouldn't let her kill me, John. You always were a soppy, sentimental sort. But I will find you again. And I will kill you."
   "Not on the best day you ever had," I said calmly. "I'm getting very close to my mother now, Penny. Get in the way of that, and someone will quite definitely kill you."
   Bad Penny looked startled, then turned and walked quickly away, moving quite rapidly for someone in a clinging dress and high heels, and soon she was lost in the shadows at the end of the street. I watched her go and allowed myself a small smile. I couldn't kill her in cold blood, but I wasn't above putting a good scare into her. Sentiment only goes so far. And I wasn't too worried about her following us. It felt like we were getting near the end of the quest. I knew where we had to go next.
   "Where are we going next?" said Madman, joining us in spirit at least. "Anywhere fun?"
   "Not really," I said. "I'm pretty sure we need to go and see the Lord of Thorns."
   Sinner gave me a hard look. "Correct me if I'm wrong, John, but I thought we'd agreed that was a really bad idea? I mean, ten out of ten for ambition, courage, and lateral thinking, but minus several thousand for self-preservation. The Lord of Thorns ... Possibly the oldest Being in the
   Nightside who still inhabits this level of reality, and the most powerful. I only mentioned him in Rats' Alley because Herne brought him up. I didn't really expect to be taken seriously."
   "The Lord of Thorns," said Pretty Poison. "We know of him in Hell. They say he knew the Christ. They say angels and demons are forced to kneel in his presence."
   "And if anyone should know the beginnings of the Nightside, it will be him," I said. "He was here before the Romans made Londinium into a city. And just maybe, Walker had Penny kill Herne for a reason; so he wouldn't point us in the direction of the Lord of Thorns."
   "This is a really bad idea," said Madman, and we all looked at him sharply, but he had nothing more to say.
 

Eight -  I Am the Stone That Breaks All Hearts

   I had a lot on my mind as I led my companions back through Freak Fair, not least trying to remember whether I'd updated my will recently. I'd always meant for Cathy to inherit my business if, or more likely when, something happened to me, but I'd never actually got around to putting it in writing. Changing your will is one of those things you always put off because you don't like to be reminded of your own mortality. You always think there's plenty of time ... until you find yourself on your way to a meeting with the Lord of Thorns. Part of me wanted to phone Cathy, talk to her one last time, but the sensible part of me overruled it. What could I say, except Good-bye?
   My companions didn't seem too worried. Sinner and Pretty Poison were strolling along hand in hand, giggling like teenagers again, and Madman was off in his own private world. I had tried to explain to them just how dangerous this was going to be, and they'd smiled and nodded and said they quite understood, but they didn't. Not really. Or they would never have agreed to accompany me to the World Beneath. Part of me wanted to forbid them to come, for their own protection, but another more practical part over-ruled it. I was going to need their help if I was to survive this last part of my journey. Was I really prepared to sacrifice them, to learn the truth about the Nightside, and my mother?
   Maybe. It wasn't like they were my friends or anything. Perhaps that's why I'd chosen them for this case—because it wouldn't matter to me so much if I had to throw them to the wolves.
   The cold-bloodedness of that thought shocked even me, and I looked around for something to distract me. And that was when I finally noticed that all of Walker's watchers had reappeared, gathered together at the far end of the street and staring at us openly, not even trying to conceal themselves. They huddled together for comfort as I and my companions approached, but looked ready to defend themselves at a moment's notice. The combat magicians actually traced protective sigils on the air between them and us. They blazed brightly, sparking and dripping eldritch fires. I came to a halt a respectful distance away and considered the watchers thoughtfully.
   "Told you we should have killed her," said Pretty Poison. "Bad Penny always was a tattle-tale. She's told them where we're going."
   "They're upset, scared, and demoralised," I said. "Just how I like Walker's people. Now watch, and learn." I took another step forward, and they all flinched visibly. I gave them my best enigmatic smile. "Hi, guys, I've got some good news and some bad news. The bad news is yes, we did just kick Bad Penny's arse and send her home crying; and yes, we did just destroy the Lamentation; and yes, we are off to see the Lord of Thorns. The really bad news is that I lied about there being any good news. Any questions?"
   Pretty much as one, the watchers decided that they really needed to return to Walker to ask for fresh instructions, and within moments they were all gone. The Jesuit demonologists actually departed running.
   "Now that is worrying," said Sinner.
   To meet with the Lord of Thorns, you have to go underground. There's a whole system of extensive catacombs, tunnels, canals, and sewers deep under the streets of the Nightside, usually referred to as the World Beneath. It is inhabited by people, and others, who can only exist and move in darkness, away from the open skies and hot neon of the streets above. You can be born, live your whole life, and die in the World Beneath, and countless have down the centuries. The dark tunnels and canals also provide a means of getting back and forth in the Nightside without being observed. They're not much used for general travel, because those who live in the World Beneath tend to discourage it, by killing and often eating those who annoy them. And they're easily annoyed.
   But, it was the only way to reach the Lord of Thorns' domain. I'd never been there myself. Didn't even know anyone who'd been crazy enough to try. But sometimes I make it a point to be paid in secrets as well as hard currency, because you never know when even the most obscure piece of information will come in handy while working a case. The man who told me about the Lord of
   Thorns, and the World Beneath, no longer had any eyes. They'd been bitten out. He told me in a harsh whispering voice of a darkness deeper than the night, of tunnels that went on forever, and silent folk who passed through arching catacombs like worms in the earth.
   There are no advertised entrances to the World Beneath. Either you know where to find them, or you don't need to know. I led my people through a series of increasingly narrow and ill-lit streets, where people scuttled away to hide in the shadows when they saw us coming, to the nearest entrance I knew of—a small private garden, held inviolate behind heavy stone walls accessed only by a securely locked gate. I studied the garden through the spiked iron bars; it seemed a pretty enough place, lit by flaring gas jets. Like finding a single perfect lily floating on a cesspit. There were trees and flowering shrubs and rich blooms laid out in attractive displays. A thick, heady perfume drifted through the gate to me. Pretty Poison snuggled in close beside me.
   "What's a pretty place like this doing in an area like this? And why is this gate absolutely crawling with protective spells?"
   "The Nightside is full of surprises," I said. "And mysteries are our food and drink."
   "You mean you don't know," said Sinner.
   "Got it in one," I said. "But I do have a key. Part payment from an old case."
   "Which you're not going to tell us about," said Pretty Poison.
   "The world is not ready to know," I said solemnly.
   "You are so full of it," said Madman. We all turned sharply to look at him, but he had nothing more to say.
   I took the key off my key-ring, and turned it in the gate's lock. It didn't want to turn, and I had to put some muscle into it, but finally it lurched into place, and I pushed the gate open. I could feel the protective spells deactivating, like a sudden release of tension on the air. I stepped aside to let the others go in first. Not entirely out of courtesy; I didn't trust the garden. When nothing immediately awful happened, I followed them in and shut and locked the gate behind me.
   Blue-white light from the impossibly huge moon overhead gave the garden an unreal, ghostly look. The trees were tall and spindly, stark silhouettes against the butter yellow glow of the old-fashioned gas jets set high on the walls. A single narrow path of beaten earth curved back and forth through the garden, between hulking bushes and shrubs and past intricate displays of night-blooming flowers. Everything in the garden was moving slowly, though there wasn't a breath of breeze. Even the petals of the flowers opened and closed, like pursing mouths. The flowers were mostly white and red, and something about them made me think White for bone, red for meat.I once heard a rose sing, and it was the most evil thing I've ever heard.
   "Nice place," said Sinner, stooping to sniff a flower. He then pulled his head back quickly, wrinkling his nose.
   "No," said Pretty Poison. "I don't think so."
   "Top marks for insight to the demon from Hell," I said. "Everything here has really deep roots. You don't want to know from what they draw their nourishment. Now let's all head for the statue in the middle of the garden; and don't touch anything."
   The narrow path wound back and forth, to make sure everything in the garden got a good look at us, but finally it brought us to the statue of an angel, kneeling and weeping over its torn-off wings. The features on its face had been eroded away, by wind and rain and time, or perhaps just by tears. Behind the angel was a moon-dial, showing the exact right time. I took hold of its pointing gnomon with a firm hand and turned it slowly through one hundred and eighty degrees. The whole moon-dial shuddered violently, then slid jerkily to one side to reveal a dark shaft, just big enough to take a man, falling away deep into the earth. A black metal ladder clung to one side of the shaft. We all took it in turns to stare dubiously down into the darkness, then Pretty Poison summoned up a handful of hell-fire. She held the leaping flames out over the shaft, but the light didn't penetrate far. In the end, we made her go down first, so she could carry the light ahead of us. None of us liked the idea of descending blindly into that dark.
   So she went first, then Sinner because he wouldn't be parted from her, then Madman, and finally me to keep Madman moving. The heavy rungs of the metal ladder were hot and sweaty under my hands, and the narrow circle of light above soon disappeared into the distance. The light below, now dancing at Pretty Poison's shoulder, was barely enough to let us see each other. I didn't like the colour or the texture of the hell-fire; it made me feel... uneasy. I made myself concentrate on the ladder. The rungs had been set uncomfortably far apart, as though not designed or intended for human use. My shoulders bumped against the sides of the shaft as I descended, and the ladder seemed to fall away forever. Down and down we climbed, until my arms and legs ached from the strain, and still there was no sign of any bottom to the shaft. I would have liked to change my mind and go back up, but I didn't think I had the strength to climb up that far, so all that was left was to keep going down. We were all breathing hard, the harsh sounds loud on the quiet.
   When Pretty Poison suddenly announced that her feet had hit bottom, we all cried out in relief, even Madman. He seemed more with us,of late. Perhaps he just needed shared company and events to ground him; or perhaps he sensed some danger coming, so great he needed to be more focussed to deal with it. I wasn't about to ask. I just knew he would say something that would make my head hurt. One by one we climbed down out of the end of the shaft and emerged onto a bare path beside a canal; dark waters in a dark place. The stone wall on the other side of the canal showed huge claw marks, gouged deep into the stone by something monstrously large. There was no sign of anyone or anything for as far as Pretty Poison's leaping flame could carry, except for a small silver bell hanging from a tall support. The four of us stood together on the narrow bank, huddled close for comfort. We could all tell we'd come to a really bad place. The air was hot and sweaty, like a fever room, and it smelled bad. Spoiled.
   "Now what?" said Sinner. His voice didn't echo, or carry.
   "I suppose we ring the bell," I said. "This is as far as my knowledge takes us. From now on, it's all unknown territory."
   "Ring the bell?" said Sinner. "How do we know it doesn't just announce to the local nasties that lunch has arrived?"
   "We don't," I said. "Feel free to chime in with any other ideas you may have. Besides, what have you got to be worried about? You're supposed to be invulnerable."
   "Not exactly. Just very resistant to punishment. I'm not sure even I could survive being eaten, digested, and excreted by something sufficiently large and determined. I am a unique case, but even I have my limits."
   "Now he tells me," I said.
   "Boys, boys," said Pretty Poison. She was kneeling at the edge of the canal, holding her flame-covered hand out over the dark waters. "I'm pretty sure I saw something move in here... Do you suppose they have alligators down here? You hear stories, about pets being flushed away..."
   "I have a strong feeling that whatever lives in these waters would probably consider alligators an appetiser," I said firmly. "I'd back away if I were you. Slowly and very carefully. This is where all the things too nasty for the Nightside end up."
   "Ring the bell," said Sinner.
   I gave it a good hard ring, and the sharp, almost painfully intense sound travelled up and down the canal, without any trace of echo or distortion. We all braced ourselves, ready for whatever attack might lurch forth out of the darkness, but nothing happened. The sound died away, and all was still and quiet. We all slowly relaxed again. I realised that Madman's personal sound track had shut itself down sometime back. Presumably because it couldn't come up with anything appropriate. And then, from out of the darkness to our right, further down the canal, came the sound of something moving. The slow steady sound of some craft ploughing through the dark waters. We all stared, straining our eyes against the gloom, until finally a low-bottomed barge appeared, in a warm golden glow that surrounded it from stem to stern. It headed unhurriedly towards us, a single human figure standing amidships, poling the barge along with a solid silver staff. The barge was a good twenty feet long, painted a cheerful pastel blue, with big black eyes delineated on either side of the pointed prow. The human figure propelling the barge with his efforts wore a concealing scarlet cloak and a featureless pale cream mask that covered all his face. Disturbingly, the mask only had one eyehole, the left. The barge slid to a halt before us, and the cloaked figure gave us a deep, formal bow.
   "Welcome to the World Beneath, you poor damned fools," he said, in a deep resonant voice with more than a hint of a French accent. "Where do you wish me to take you? Not that there is a lot of choice, I'll admit. Upstream is bad, downstream is worse, though at least the Eaters of the Dead have been quiet lately. Someone tried putting poison down a while back, but the rotten buggers positively thrived on it. I hope you've got a specific destination in mind, because I don't do tours. I'd go back up, if I were you. It doesn't get any better, the deeper in you go."
   "Pretty much the kind of welcome I'd expected," I said, when I could finally get a word in edgeways. "Can you take us to the Lord of Thorns?"
   "Is life really that bad?" said the bargeman. "There are easier ways to kill yourself, and most of them are a lot less painful."
   "The Lord of Thorns," I said firmly. "Yes or no?"
   "Very well, my friends. Climb aboard. Don't fall in the water. The natives are restless, and very hungry."
   We all boarded his barge very carefully, and it hardly rocked at all under our weight. The bargeman pushed his silver pole into the water and started us on our way with one long, effortless movement. There was more to him than there seemed, but then, there would have to be. Surrounded by the golden glow of the barge, Pretty Poison doused her hell-fire, and we all relaxed a little. The barge moved silently and easily on into the enveloping dark. The bargeman stared straight ahead, but whatever he saw with his single eye, he kept to himself.
   "Don't get many tourists down here these days," he said, his voice quite distinct behind the pale mask. "Not that we ever did have many visitors, and for the most part we like it that way. Peace and quiet's a wonderful thing, you know? Are any of you famous? I don't keep up on the gossip like I used to."
   "This is Sinner," I said. "This is Pretty Poison, and that is Madman. I am John Taylor."
   The bargeman shook his head. "No. Sorry. Means nothing to me. I had that Julien Advent in my barge once. A real gentleman, he was."
   "How long have you been down here?" I asked.
   "I have no idea. And don't tell me, because I don't want to know. It was the beginning of the twentieth century when I first came to the Nightside, boarding the newly opened subway from Paris with a howling mob hot on my heels. I soon found my way down here. I'd had enough of the hurly-burly of city life, and wished only solitude. I do miss the opera, though ... Still! I provide a service here, to keep myself occupied, and as a small act of penance for the days of my hot-headed youth."
   "What can you tell us about the World Beneath?" said Sinner.
   "Parts of it are as old as any other part of the Nightside, and as dangerous. It started out as a collection of sewers, canals, and offshoots of the Thames, covered over by the growing city, running through and around a huge system of catacombs built by the Romans, so they could do things down here that the world above wouldn't approve of. Very practical people, the Romans. They believed that if the gods couldn't see what you were doing, it didn't count. Lot of people in the World Beneath still think that way, though of course I use the term peoplevery loosely. We have quite a population down here, these days. Solitudes, of course; religious types sitting in dark stone cells for the good of their souls. Then there's the odd type who just can't get on with anyone, even in the Nightside. And those on the run, like my good self. The Subterraneans have been down here for centuries, making their own little city out of the catacombs. Don't bother them, and they won't sacrifice you to their gods. Then there's vampires and ghouls and various offshoots of the Elder Spawn... We get all sorts down here. But don't you worry yourself about them, my friends. My barge and I are protected, by old custom. You sit tight, and I'll bring you right to the Gate of the Lord of Thorns' domain. And after that—may God have mercy on your souls, because it's a safe bet the Lord of Thorns won't."
   "Have you ever met him?" said Sinner.
   The bargeman snorted loudly behind his mask. "No. And the odds are you won't get to, either. He is very well guarded."
   He poled us along the canal for some time, singing snatches of grand opera and saucy French drinking songs in a fine baritone voice. Madman's sound track joined in, producing perfect harmonies and descants. Things came and went in the dark waters, occasionally bumping against the sides of the barge, but never breaking the surface of the water. The golden glow surrounding the boat was just bright enough for me to make out the strange astronomical symbols carved into the curving stone ceiling above us. Star systems never seen from earth, in this or any other time. Pretty Poison snuggled in close beside Sinner, ignoring the surroundings to murmur in his ear. He didn't respond, except to sometimes shake his head.
   The barge finally slowed to a halt beside a section of the canal bank that at first glimpse seemed no different from any other. The masked bargeman leaned on his pole, and looked thoughtfully about him.
   "This is as far as I can take you. A bad place, my friends. I would say au revoir; but I doubt we'll meet again."
   They disembarked, and he pushed the barge away from the bank and set off back the way we'd come. He wasn't singing any more. The golden glow departed with the barge, replaced by a sullen red glare emanating from a high archway set into the dark stone wall. Ancient Greek characters had been etched into the cracked and pitted stone slabs that made up the arch. We all looked at each other for a while, then Pretty Poison tutted loudly.
   "No-one studies the classics any more. Allow me. Translating very freely, it says, Meat is Murder."
   "Wonderful," said Sinner. "We have fallen among vegetarians."
   "Somehow I rather doubt it," said Pretty Poison. "I can smell rot and decay and the corruption of living things. And the smell is wafting out of this archway."
   I could smell it, too. A heavy, noxious smell that left a bad taste in the mouth. Like a charnel-house left to simmer in a hot sun. It was definitely drifting out of the open archway, even though there was no trace of movement in the air. A warning, perhaps ... or a threat. It didn't make any difference. There was nowhere else for us to go, except back. I led the way in, and the others followed reluctantly after me.
   A short tunnel, its curving stone walls beaded with sweat, soon gave way to a fair-sized cavern hollowed out of the living rock. Big enough to hold a fair-sized congregation, but not of any church you'd choose to visit. Butcher's tools hung down from the ceiling on wires, saws and knives and skewers, all of them stained with old, dried blood. At the far end of the cavern was a crude throne, made up of slabs of meat, some of it fresh, most clearly spoiled, all of it surrounded by a great cloud of buzzing flies. And all the walls of the cavern were covered in people's names, drawn spikily in blood, from a wide variety of languages and cultures.
   "The names of those who came before us?" wondered Sinner.
   "I don't know if anyone else has noticed," said Pretty Poison. "But there doesn't seem to be any other way out of here."
   "I'd noticed," I said.
   "This isn't at all how I'd pictured the Lord of Thorns' domain," said Sinner. "I think there is a strong possibility that we've been had, people."
   "I don't think so," Pretty Poison said slowly. "We're not alone here."
   The cloud of flies rose up suddenly from the meat throne, buzzing angrily. They swirled around the cavern horribly quickly, while we ducked our heads and swatted at them with flailing hands, then the cloud returned to the meat throne, swelled in size and took on a roughly human shape. It stood on stocky legs, a dark blocky shape towering over us, its unfinished head brushing against the cavern ceiling. And then it sat down abruptly on the meat throne, and the heavy buzzing gradually resolved itself into something like human speech. It sounded foul and hostile, a mockery of language.
   "Welcome, dear travellers," said the flies. "You have found your way to the entrance to the domain of the Lord of Thorns. And this is as far as you go. He does not wish to be disturbed. And so he has set me here, a demon summoned up out of Hell and bound to this place, just to ensure he gets his rest. A Prince of the Pit, damned to obey a servant of Heaven, until the Nightside is destroyed or Time itself runs out. Sometimes I think the whole universe runs on irony. Still, the eating's good. Hello, Pretty Poison. It's been a while. How do you like my place? It's not much, but it has some of the comforts of home."
   "Hello, Bub," said Pretty Poison. "How is it that thou art bound here, to a mortal's purpose?"
   "Because he is the Lord of Thorns and knows much that is forbidden. Is that your Sinner with you? The only soul that still loved in Hell?"
   "Yes," said Pretty Poison. "This is my dear Sidney."
   "Pervert," the demon said to Sinner. "And fool, to still believe in Hell's lies. She will corrupt you and drag you back down into the Pit. It's what she does. And she has always been very good at her job."
   "Given enough time, and sufficient motivation," said Sinner, "I could probably swat you to death."
   I decided to intervene, before the conversation could deteriorate any further.
   "Hi. I'm John Taylor. No doubt you know the name. I'm here to speak with the Lord of Thorns. So step aside, or I'll think of something amusing to do to you."
   "John Taylor?" The writhing shape leaned forward on its meat throne to get a better look at me. "I'm impressed. Really. Though I'd always thought you'd be taller. But it's more than my job's worth to let you pass. Pride in my position is pretty much all I have left here. And whatever you might do to me would be nothing compared to the torments the Lord of Thorns would visit on me. I am bound to this place, and to his will. Besides, it's been a long time since my last visitor, and I'm hungry."
   The dark shape stood up abruptly, and huffed and puffed itself up into a great hulking figure, taking up half the cavern, buzzing almost painfully loudly. It tried to pick up Madman with one huge black hand, but the flies just slipped harmlessly past him. The demon hesitated a moment and thrust a hand in my direction. The fingers extended, becoming shafts of flies rushing towards my face. They swept over me, trying to force their way into my mouth, nose, ears, and eyes. I panicked, flapping my hands wildly about my head while pressing my lips and eyelids firmly together, as the flies crawled over my face. And then to my astonishment they all leapt off me and retreated, apparently repulsed. The demon froze where it was, seemingly just as astonished as I was, and I seized the moment to summon up my gift. My inner eye snapped open, and it only took a moment for me to find and identify the Words of Power that bound the demon to this place.
   (And yet even as I used my gift, some instinct made me slam my inner eye shut again, the moment it was no longer needed. While my mind was open and vulnerable, I sensed Something awful closing in on me, trying to pin down my location so it could manifest. My enemies had found something worse than the Harrowing to send after me, and all my instincts screamed that if I were to use my gift one instant longer than necessary, this new horror would find me and carry out its makers' terrible intent.)
   I said the Words of Power. They arose from no human tongue, or even human sounds, and just to hear them said aloud would reduce most men to madness. I said the Words, slowly but distinctly, forcing them out syllable by syllable, and the terrible sound of them reverberated in my skull until I thought they'd blow my head apart. The demon screamed in thwarted rage, then was gone, taking with him his meat throne and his butcher's tools. All that remained was the sullen red glare, and the names of his victims traced on the cavern walls in their own blood.
   Pretty Poison looked at me, taken aback. "How is it that you were able to speak those Words? The sheer power involved should have blasted the soul right out of your body."
   "I have hidden depths," I said. My throat hurt. Where the meat throne had stood, there was now an opening in the cavern wall. "And so, it seems, has this place."
   We all moved cautiously forward to study the new opening. It was shaped like a door, with smooth sides and top, but that was all there was to it. No warning signs, no welcome mat. Beyond the opening lay a long, descending stairway, carved into the rock face of a vast open space. Hovering lights marked the stairs here and there, but their pale light did little more than show just how far down the steps went. It looked like a hell of a long way. There was no railing, nothing between the open edge of the steps and an impossibly long drop. I started down the steps, one shoulder pressed firmly against the rock face, and after a moment the others followed me. We descended into the dark abyss, step by step, for a very long time.
   "Are we there yet?" said Madman.
   "Shut up," I said.
   "Are we even still under the Nightside?" said Sinner. "We do seem to have travelled rather a long way."
   "We haven't left the Nightside, sweetie," Pretty Poison assured him. "I'd know."
   "We are in the dark places of the earth," said Madman. "Where all the ancient and most dangerous secrets are kept. There are Old Things down here, sleeping all around us, in the earth and in the living rock, and in the spaces between spaces. Keep your voices down. Some of these old creatures sleep but lightly, and even their dreams can have force and substance in our limited world. We have come among forgotten gods and sleeping devils, from the days before the world settled down and declared itself sane."
   "I think I liked it better when you made no sense at all," said Sinner.
   The hovering lights turned out to be paper lanterns, nailed to the rock face at regular intervals. Their tightly stretched sides were made up of silently screaming faces. The eyes in the agonised faces turned to watch us as we passed.
   "Are they still alive?" I said. "Still suffering?"
   "Oh yes," said Pretty Poison, her voice heavy with a certain satisfaction.
   "Hush," said Sinner.
   "But what are they?" I said. "Who were they?"
   "Uninvited guests," said Madman, and after that no-one felt like talking for a while.
   We descended further and further into the earth. The stairs wound around the curving wall of the vast abyss. The dark rock of the wall showed clear signs of having been worked on long ago, at first by tools but later by what seemed to be bare hands. Someone had fashioned this great gulf under the Nightside for a purpose, but who and why and when remained a mystery. Could men have done this, alone or with help? Why would they have wanted to? Was the Lord of Thorns really so dangerous that they had to bury him this deep in the earth? The deeper I went, the more scared I became. My hands were trembling, and my mouth was dry. This was all getting too big, too important for me. I wanted to go back to being just another private investigator, dazzling the natives with tricks and mind games, trading on a reputation I'd never really earned. But I had to go on. I'd come this far for the truth, and though I'd run out of courage and good sense, stubbornness kept me going.
   The wall at my shoulder became increasingly pitted and corroded, and thin streams of liquid trickled down the dark stone. I stopped and studied the wet surface closely.
   "Don't touch it," said Sinner.
   "I wasn't going to. What do you suppose this is? Acid rain, or the underground equivalent?"
   "No," said Pretty Poison. "Tears."
   Sinner looked at her dubiously. "You know this place?"
   "Of it. All demons and angels are warned about this place. We are almost at the domain of the Lord of Thorns, the Overseer of the Nightside."
   "The Overseer?" I said. "Does that mean he's the one behind the Authorities?"
   "No," said Pretty Poison. "He's much more powerful than that. He sits in judgement, and mercy and compassion are not allowed to him."
   "I want to go home," said Madman.
   "Most sensible thing you've said all day," said Sinner.
   The stairs finally curved around a corner and came to an end, facing a great and elegant chamber carved out of crystal. A pleasant, comfortable light appeared suddenly overhead, bursting out of one crystal facet after another, until the whole chamber was bright as day, like standing in the heart of a huge diamond. In the centre of the crystal cave was a single raised slab of polished stone, and on that slab, sleeping peacefully, a man. He didn't look particularly dangerous, with his grey hair and grey robes, and a calm face apparently untroubled by care. We all filed into the shining chamber, looking uncertainly about us. I think we'd all been expecting more guardians, more defences, but everything was still and quiet. Like the eye of the storm.
   Etched into every crystal facet were characters from the language known as Enochian, a tongue created for men to speak to angels. I recognised it, but I couldn't read it. Not many can. It is corrosive to rational thinking. Pretty Poison moved along one wall, tracing the characters with a fingertip.
   "These are names," she said softly. "Names beyond number, of angels from Above and Below, from all ranks and stations ... Even ray name is here. My true name, from before the Fall. No mortal should have access to this knowledge..."
   "But... why write them here?" said Sinner.
   "Because to know the true name of a thing is to have power over it," said Pretty Poison. 'To command and to control. Whoever put the Lord of Thorns here, and made him Overseer of the Nightside, has given him power over all the agents of Heaven and Hell."
   "No wonder he was ripping the wings off angels during the angel war," said Sinner. "But who could give him that kind of power?"
   'Two possibilities come to mind," said Madman.
   "Shut up," said Pretty Poison.
   She sounded shocked, upset. I was concentrating on the man on the slab. He hadn't moved at all since we entered his domain. But I didn't think he was sleeping. Sleeping people usually breathe now and again. And then my heart missed a beat as he sat up abruptly, swinging his legs over the side of the slab, and sat facing us. We all froze where we were, caught in the gleam of his gaze, like burglars picked out by torchlight in a place they should never have entered. With his long grey robes, hair, and beard, the Lord of Thorns looked like nothing so much as an Old Testament prophet. The kind that told you the Flood was coming, and you'd left it far too late to book seats on the Ark. His face looked older than any man's should, and his eyes were fierce and wild and touched with a divine madness. His presence filled the crystal cave, and under his gaze we all flinched and felt unworthy.
   Except, of course, for Madman, who shouted Daddy!and tried to climb into the Lord of Thorns' lap. We all grabbed him, and dragged him away by brute force. And then one by one, we knelt before the Lord of Thorns. His presence demanded it. Madman shrugged, and knelt with us. I kept my head down and tried to look penitent. This was a place of judgement. I could feel it. And judgement without mercy or compassion is always to be feared.
   The Lord of Thorns stood up slowly, his joints cracking loudly, and I risked a quick look. He was leaning on a simple wooden staff, and I felt something inside me shudder at the sight of it. Word was the wood of that staff had been taken from a tree grown from a sliver of the original Tree of Life, brought to England in Roman times by Joseph of Arimathea. There were those who said the Lord of Thorns wasJoseph of Arimathea. He looked old enough. When he finally spoke, his words sounded like rocks grinding together.
   "I am the stone that breaks all hearts. I am the nails that bound the Christ to his cross. I am the arrow that pierced a King's eye. I am the necessary suffering that makes us all stronger. The cold, clear heart of the Nightside. It was given to me to have dominion over all who exist here, to protect the Nightside from itself. I maintain the Great Experiment, watching over it, and sitting in judgement on all who might seek to disrupt or tamper with its essential nature. I am the scalpel that cuts out infection, and the heartbreak that makes men wiser. I am the Lord of Thorns, and I know you all. Sinner, Pretty Poison, Madman, and John Taylor. Stand up. I've been waiting for you."
   We rose to our feet again, glancing uncertainly at each other like children brought unexpectedly before the headmaster. I made myself speak up. Because if there's one thing I've learned from dealing with the Nightside's major players, it's that it doesn't matter how frightened you are, you can't let them know it, or they'll walk right over you.
   "So," I said. "Are we here for judgement?"
   "No," said the Lord of Thorns. "You are welcome in this place, John Taylor."
   I felt a great rush of tension flow out of me, but I didn't let him see that either. I looked at him narrowly. "Lot of people think I'm a threat to the existence of the Nightside. Are you saying they're wrong?"
   "No. Just that you're a special case." And then he smiled, just a little. "And no; I don't know why. You're as much a mystery to me as you are to everyone else. And if you find that infuriating, think how it makes me feel."
   He smiled round at all of us, and just like that the pressure of his presence disappeared. The Lord of Thorns wasn't one bit less impressive, but at least no-one felt like they might be destroyed at any moment. The Lord of Thorns stretched his back, like a cat that's been sleeping in the sun too long.
   "You've come a long way for answers," he said. "I wish I could be of more help. But truth be told, I'm just a functionary, a servant of the Nightside. Powerful beyond hope or reason, yes, because I need that power to enforce my will. But still in the end just an old, old man, unable to put down a burden he has carried for far too long. I am the heart that beats in every action and decision that makes up the Nightside, and I'm getting bloody tired of it. So ask your questions, John Taylor, and I will answer what I can. Perhaps because it's the only form of rebellion still left to me."
   "Excuse me," said Sinner, very politely, "but what about the rest of us? Are we also immune to your judgement?"
   "You don't matter," the Lord of Thorns said calmly. "Only John Taylor matters. Though you three are unique in the whole of the Nightside, in that it has been given to you, for various reasons, to shape your own destinies. This has been decided where all the things that matter are decided—on the shimmering plains, in the Courts of the Holy. I have no power over you—sinner, demon, madman." He looked at them thoughtfully, then at me. "You chose your companions for this quest wisely. No others could or would have escaped my judgement. Now ask your questions."
