"Given the clear potential for things to get really nasty really quickly, I'm surprised the Authorities haven't stepped in to confiscate the butterfly," I said, frowning. "Walker doesn't normally approve of anything that threatens to upset his precious status quo."

"Walker might like to think he's in charge of things round here," Wilde said dismissively, "but the Authorities have always understood that free enterprise has to come first."

"Philistines," said Grave, polishing her monocle furiously.

"Or," I said, "perhaps the Authorities don't believe this butterfly is the real thing, either."

Wilde smiled widely and blew a perfect smoke ring. "Don't care was made to care, darling."

By now the bidders had started filing in and were already squabbling over who had rights to seats in the front row. I politely excused myself to Wilde and Grave, and took a stroll round the perimeter of the Hall while I watched the crowd assemble noisily. Most were just anonymous faces, there to represent people or interests who didn't care to be publicly identified, or just the usual hopeful souls in search of a bargain. Some were clearly celebrity spotters, there to see history being made by the butterfly's sale. It ended up as quite a large crowd, filling all the seats and leaning against the walls. The teddy bears had to bring in more chairs, grumbling audibly under their breath as they did so. (There were human staff on hand to pass out the glossy sale brochures; apparently the bears considered doing so beneath their dignity.) The crowd buzzed with talk, of a more or less friendly kind, and there was much craning of necks to look at the butterfly, or spot rival bidders. Lucretia Grave stepped up behind her auctioneer's podium and gestured for silence with her gavel as Wilde stood proudly behind her butterfly's display case. I lurked at the back of the Hall, watching the crowd.

And then everything stopped as a huge shaggy Yeti stomped into the Hall. It was a good eight feet tall, with vast, rolling muscles under its grubby white pelt. Everyone shrank back as the great creature lumbered down the aisle, grabbed the Yeti's-foot umbrella stand, glared menacingly at one and all, then stomped out again. No-one felt like trying to stop it. After a discreet pause, to be sure the Yeti was gone and wouldn't be coming back, the auction finally got under way.

Grave started with the lesser items, and they all went fairly quickly under the hammer. Everyone was impatient to get to the star item. I concentrated on studying the more famous faces in the crowd. I wasn't surprised at Jackie Schadenfreud's presence, right in the middle of the crowd. Jackie was an emotion junkie, and I could see him savouring and sucking up the various moods of the crowd as they washed around him. Jackie had insisted on making himself known to me when he arrived, shaking me by the hand and hanging on to it just that little bit too long. He was fat and sweaty, with a twitchy smile and watery eyes. He wore a Gestapo uniform, all black leather and silver insignia, along with a Star of David on a chain round his neck. Just so he could soak up the emotions those conflicting symbols evoked. To protect him from the many who might feel outraged, Jackie was always accompanied by an oversized Doberman that he'd had dyed pink.

Sandra Chance, the consulting necromancer, had stalked into the Hall like she owned the place, but then she always did. Chance had raised arrogance to an art form. She commandeered a seat in the front row, right before the podium, as hers by right, and no-one challenged her. Few ever did. Chance was tall and slender, unhealthily pale under a mop of curly red hair, and wore nothing but crimson swirls of liquid latex, splashed all over her long body apparently at random. (Supposedly the liquid latex was mixed with holy water and other things, for protection.) She also had enough steel piercings in her face and body to make her a danger during thunderstorms. A simple leather belt covered in Druidic symbols hung loosely around her waist, carrying a series of tanned pouches that held the tools of her trade; grave dirt, powdered blood, eye of newt and toe of frog. The usual. I watched her very carefully. She ignored the lesser items as they went under the hammer. She was just there for the butterfly, and everyone knew it. Her face was all sharp angles, with cold intelligent eyes and a grim smile, and I knew her of old.

Chance specialised in cases where someone had died, usually suddenly and violently and very unexpectedly. She could get you answers from beyond the grave, if you weren't too fussy about the methods involved. I worked a few cases with her, back in the day, but we didn't get along. She only cared about getting results, and bad luck to anyone who got in her way, I used to be like that, but I like to think I've moved on. To me, Chance was a reminder of bad times—and two people I wasn't very fond of. She looked round suddenly, and caught my gaze. She'd always had good instincts. She nodded frostily, and I nodded back, then we both looked away again.

Chance currently had a relationship with one of the Nightside's more disturbing major players; that terrible old monster called the Lamentation. Sometimes known as the God of Suicides or the Saint of Suffering. Just saying its name aloud had been known to push people over the edge. No-one knew exactly what kind of relationship Chance had with the Lamentation, and most people with an imagination were afraid even to guess. Some things just aren't healthy, even for the Nightside. Chance had never shown any interest in auctions before, to my knowledge; so, could she be bidding on behalf of the Lamentation? Perhaps. But what would the God of Suicides want with the chaos butterfly? Nothing anyone else would want or approve of, certainly. I wondered if perhaps I ought to do something. After all, who'd be crazy enough to bid against an agent of the Lamentation? And then I looked around me and relaxed a little. There were more than enough major players here to stand against Chance, especially if they got caught up in bidding fever.

And if by some malign chance she did end up winning, I could always do the public-spirited thing—steal the butterfly and run like hell.

Sitting not far away were the Lord of the Dance and the Dancing Queen, ostentatiously not talking to each other, on principle. Odds were neither of them actually wanted the butterfly; they just didn't want the other to have it. Once handfasted, now divorced, they each led very separate dance religions. The Lord of the Dance was currently boasting an ethnic Celtic look, complete with woad and ritual scarring, while the Dancing Queen stuck to her beloved disco diva look. It was always a joy to watch them enter a room, their every movement graceful and poised and significant, as though they were moving to music only they could hear.

Among the last to arrive had been the Painted Ghoul, openly there to bid on behalf of the Collector. (Who was too proud to appear in person, having been caught trying to steal things on three separate occasions.) The Painted Ghoul was the nastiest, most evil-looking clown you'd ever not want to meet in a back alley. His baggy costume was composed of fiercely clashing colours, and his leering, made-up face suggested unnameable depravities. He swaggered into the Hall like a pimp in a schoolyard, flashing a crimson grin full of teeth filed down to points.

"Hiya, hiya, hiya, boys and girls! Great to be here. I just flew in from Sodom and it ain't my arms that's tired! Anyone want to play Find the Lady? I'm almost sure I can remember where I buried her..."

He was the proverbial Clown at Midnight, the smile on the killer's face, the laugh that ends in a bubble of blood. But he was still really just a glorified errand boy, for all the airs he gave himself.

I looked round sharply as the bidding finally got to the butterfly. Suddenly it seemed like everyone was trying to bid at once. Grave did her best to keep order, but even her experienced auctioneer's eye had trouble following every raised hand or nodding head. Harsh words and even blows broke out here and there as people became convinced they were being deliberately overlooked. I strode quickly up and down the aisles, glaring people into better behaviour, but trouble broke out faster than I could put it down. Sandra Chance kept pushing the price up, but no-one looked like dropping out. The Painted Ghoul leaned back in his seat, smiling nastily as he topped Chance's bid. Others clamoured to be heard, and open brawling broke out as Grave looked desperately this way and that. The chaos butterfly was a great enough prize to fuel anyone's ambitions. I considered the situation and didn't like what I saw. The mood of the crowd was angry and frustrated, and on the verge of getting really nasty. The Hall's built-in wards would prevent any magical attacks but couldn't do anything to stop a gun or a knife. And whoever ended up winning, it promised to be trouble. It looked like I was actually going to have to do something. Usually I could get away with a quiet word and a harsh look, and rely on my reputation to calm things down, but we were already well beyond that.
