You can find anything in the Nightside, from the sacred to the profane and back again, but I don't recommend attending the auctions there unless you've got a strong stomach and nerves of steel. I don't normally go to auctions any more, even though most people are afraid to bid against me. I always end up saddled with a crateful of junk, just to get the one thing I do want. One time I accidentally acquired a Pookah, and for a few months I was followed around the Nightside by a Playboy Bunny Girl invisible to everyone except me. Fun, but distracting.

However, when you work as a private investigator in the Nightside, that hidden magical heart of London, where gods and monsters walk side by side, and sometimes attend the same self-help groups, some cases almost in evitably lead you to the most unpleasant places. The head auctioneer of the Night side's Great Auction Hall hired me to stand watch over one particularly contentious auction, to keep the bidders in line. It sounded straight forward enough, which should have been a warning. Nothing's ever straight forward in my life.

I turned up nice and early, so I could look the place over. It had been several years since I was last there, and in between I'd left the Nightside on the run, with a bullet in my back, and reluctantly returned to stage a semi-triumphant comeback. The doorman at the Hall took one look at me and didn't want to let me in, but I gave him my name, and he turned satisfyingly pale and stepped back to wave me in. A good, or rather bad, reputation will get you into places that a battalion of troops wouldn't.

The head auctioneer stopped pacing nervously up and down and came striding across the great empty Hall to greet me. She grudged me a brief smile and crushed my hand in an over-firm handshake. Lucretia Grave was a short, sturdy woman in an old-fashioned tweedy outfit, surmounted by a monocle screwed firmly into one dark, beady eye. She appeared to be in her early fifties, with a brutal bulldog face and grey hair scraped back into a really severe bun on the back of her head. She looked like she could punch her weight. She glared at me like it was all my fault, and got stuck right in.

"About time you got here, Taylor, old thing. I haven't felt safe in me own Hall since the damned thing arrived. I've had piles that gave me less problems. I know we say we'll auction anything you can find, capture, or manhandle through the doors, but some things are just more trouble than they're worth. I wouldn't have anything to do with the bloody thing, if I wasn't on commission. I've been playing the doggies again, you know how it is. Rotten animals only have to hear I've put good money on them and they immediately develop back problems and heart conditions. Still, you mark my words, old thing; this particular item is going to go for serious money." She scowled unhappily and sniffed loudly. "It's days like this I wish I was back at me old job, at Christie's. I'd go back in a second if only I could be sure the police weren't still looking for me."

I was about to ask, politely but very firmly, what the hell we were talking about, when we were interrupted by a whole bunch of six-foot-tall teddy bears, carrying in the various items up for auction that session. The bears swept straight past us, carrying the items carefully in their soft, padded arms, talking in low, growly voices. The bears all looked like they'd seen a lot of rough handling, and as they passed Lucretia Grave a few muttered loudly about the need to get unionised. They set out each object in its own glass display case, treating every item with great care and respect.

"I'd better check everything's where it's supposed to be," Grave said heavily. "They all mean well, but they're bears of very little brain. Typical bloody management, trying to save money again. You have a look around, old thing, get the feel of the place, don't touch anything."

And off she strode, like a tug-boat under full steam, to hector the bears. I let her go. It was either that or throw her to the floor, tie her up, and sit on her till I got some useful answers out of her; and I couldn't be bothered. I looked around. The Great Auction Hall had started out life as a thirteenth-century tithe barn, and had changed remarkably little down the years. The walls were a creamy grey stone, in large close-fitting blocks held together by artistry and tradition rather than mortar, rising up to soaring wooden rafters that came together in a complex latticework half-hidden in shadows. There were only slit windows in the walls, and the floor was unpolished wood, covered in sawdust. Fluorescent rods provided almost painfully bright light. There were no comforts or luxuries, but then, people didn't come here to admire the scenery. The Great Auction Hall was a place of serious business.

I walked past the rows of cheap wooden folding seats, set up to face the no-frills auctioneer's stand, and looked over the various items in their display cases. It was the usual mixture, the famous and the infamous, of dubious value and debatable provenance. You could buy anything in the Nightside, whatever your interests or pleasure, but no-one guaranteed it was necessarily what it seemed to be. You could get lucky, or you could get dead, with precious little room in between. And just because you owned a thing, it didn't mean you could always hang on to it...

The first item was a heavy thigh-bone, identified as the weapon with which Cain slew Abel. There was a letter of confirmation from the ancient city of Enoch, but you took such things with a pinch of salt in the Nightside. Next in line were three different Maltese Falcons (buyer beware), a cast-brass head of JFK that supposedly spoke prophecy, Nostradamus's quill pen, one of Baron Frankenstein's scalpels, a small lacquered wooden box that claimed it held the ashes of Joan of Arc, and a Yeti's-foot umbrella stand. The rest was just junk and tat, stuff only a collector could love. Certainly nothing I'd give house-room.

I've never believed in acquiring objects of power. They always let you down. Either the batteries run out at the worst possible moment, or you go blank on the activating word; and you can never find the instruction manual when you need it. More trouble than they're worth. And far too many of them turn out to be just bits and pieces that have hung around long enough to acquire a reputation. Not unlike me, I suppose.

I paused to study myself in a tall standing mirror in an ornate silver frame. (It was labelled The Mirror of Dorian Gray; make of that what you will.) The reflection didn't look anything special; though I supposed I did at least look like a private eye. Tall, dark, and interesting-looking, wrapped in a long white trench coat that hadn't seen a laundry anywhen recent. A bit tired and battered round the edges, maybe, but that's life in the Nightside for you. I tend to get the cases no-one else wants, the kind other investigators have the good sense to turn down, and I like it that way. I have a gift for finding things, whether they want to be found or not, a hunger for the truth, and a stubborn streak that keeps me in the game long after anyone with any sense would have legged it for the horizon.

My father drank himself to death, after finding out my mother wasn't human. No-one knows who or what my mother really was, but everyone in the Nightside's got an opinion. There are those who treat me like the Antichrist, and others who see me as a King in waiting. And, an unknown group of enemies have been sending agents to kill me ever since I was a small child.

I try not to let it go to my head.

Lucretia Grave came stomping back to join me. She was wearing the monocle in the other eye now. I wondered whether I was supposed to say something, but decided not to. Some conversations you just know aren't going to go anywhere useful. Grave started in on me again as though we'd never stopped talking.
