in yourself, too. I'd spare you that knowledge, for as long as possible. Until then, it's just too dangerous for you to join me on a case. A real case. Because you can never tell when they're going to turn dirty."

At which point we were interrupted by a whole bunch of lemmings escaping from the unseen kitchens. They'd launched a mass breakout, and came swarming across the floor of the clearing like a furry tide, while diners squealed and shouted and pulled up their feet. The lemmings climbed up onto chairs and tables and even lower tree branches, and threw themselves through the air, in fine old lemming fashion. Cathy and I cheered them on.

"Look; that one's got a parachute! That one's hang-gliding! Go, little fellow, go!"

It was all over in a few moments. The lemmings scattered into the surrounding jungle, singing high-pitched victory songs (something about Rick only having one ball), and everyone settled down again. No-one emerged from the unseen kitchens in pursuit. Lemmings were always on the menu (very nice, stuffed with locusts' legs, in a tart lemon sauce) and there were always more on the way. Lemmings breed like there's no tomorrow, and indeed for a whole lot of them, there isn't.

Cathy and I went back to contemplating our menus, watched over by the foot-tapping giant penguin, who'd developed a bit of a twitch in one eye.

"Don't touch the dodo steaks," I advised Cathy. "They're strictly for the tourists. They taste awful, no matter what kind of sauce they're trying to disguise them with this week. How about... the roc egg omelette? Feeds four. No? Well, there's always the jabberwocky giblets. They come with borogroves, but they're always a bit mimsy .... Chimera of the day? Roast mammoth; always big helpings. Or how about Hydra?"

"No," said Cathy. "Greek food doesn't agree with me."

After a certain amount of toing and froing, we finally settled on dragonburgers (flame-grilled, of course), with a nice healthy salad on the side. For dessert, Cheshire Cat ice cream. (Because it vanishes, it's not fattening.) We'd no sooner given the waiter our order than the food arrived, hot and steaming on a hostess trolley pushed by another giant penguin, wearing a name badge that said HI! MY NAME IS ... PISS OFF TOURIST. I'm convinced Rick has a precog in his kitchen. The penguins left us to our meals with a simultaneous dismissive sniff. I palmed my sliver of unicorn's horn, and surreptitiously tested both my food and Cathy's.

No trace of poison, said a snotty voice in my head. But the calories are off the scale, and it's far too salty. I thought we'd agreed you were going on a diet?

I put the sliver away. I hate chatty simulacra. Give them a steady job, and they think they're your mother.

Cathy and I ate in silence for a while. The dragon meat was delicious. Very smoky taste. Quiet conversation went on around us. It was all very civilised. When the drag-onburgers and some of the salad were just a pleasant memory, we sat back and waited contentedly for dessert. It arrived immediately, of course, and the penguin waiter quickly cleared away the dirty plates and slapped the bill on the table. (Service not included. They wouldn't dare.) When the waiter was gone, I leaned forward to talk confidentially with Cathy.

"One thing you have always been better at than me, Cathy, and that's knowing everything about the latest trends. See the gentleman in the navy blue suit and old-school tie, two tables down? What the hell is that all about?"

The man in question had a hole drilled neatly through his forehead, on through his brain, and out the back of his skull, leaving a narrow tunnel all the way through his head. You could see right down it, though I tried very hard not to.

Cathy looked, and sniffed loudly. "Ultimate trepanation. The idea was, drilling a hole through your forehead would allow the bony plates of the skull to break apart and expand, allowing the brain room to expand as well, and thus make you more intelligent. This new fad just takes the idea to its logical conclusion. Personally, I would have stuck with the smart drinks. They didn't work either, but they had to be a lot less painful."

"I would have thought deciding not to drill a hole in your head was a pretty good indication of intelligence," I said, trying not to stare, or wince. "I wonder if the hole plays music when
