We knew each other. A bit. Ships that passed in the night and kept on going. We didn't approve of each other, but we had been known to work together, occasionally. When no-one else would do.

Walker invited her to sit down at his table, and immediately the footman was there to pull her chair out for her, then push it back in again. Bad Penny accepted the attention as her due, but did deign to favour him with a flashing smile; and the footman did everything but wriggle like a puppy.

"You needn't bother with a menu," Walker said calmly to the footman. "The lady isn't stopping."

Bad Penny pouted. "Wouldn't eat here if you paid me, darling. I do have my standards."

Walker waved the footman away, and he disappeared reluctantly. I leaned out a little way from Julien's table, to hear them more clearly. Bad Penny worried me; but then, she always did, even when she was supposedly on my side. Julien watched me, amused, but continued with his dinner. As editor of the Nightside's only daily newspaper, the Night Times, he knew he'd get a good story out of me eventually.

I was just a bit surprised that Bad Penny was working for Walker. He was usually more subtle than that. Bad Penny, on the other hand, would work for anyone with enough money, on anything from espionage to assassination. Whether she was working on the side of Good or Evil had honestly never mattered to her; as she was only too happy to point out, gold has no provenance. She had no personal preference either way, nor any ethics worth the mentioning. She was utterly amoral and quite cheerful about it. I knew she'd occasionally done the Authorities' dirty work in the past, when they felt the need for a little distance or deniability. (Strictly pro bono, in return for which they agreed to turn a blind eye to some of her more notorious activities. Business as usual, in the Nightside.)

"I do hope this isn't about a honey trap, darling, because I don't do those any more," she said flatly to Walker. "They're just too easy, my dear; there's no challenge in it. Been there, done that, starred in the video. These days I prefer to specialise in cunning thefts, daring exploits, and just a touch of the good old-fashioned ultraviolence now and again, to keep the blood flowing."

"And a little discreet blackmail," said Walker. "To keep your coffers full."

Bad Penny batted her long eyelashes at him. "A girl has to live. And I never was very good at investments. All I have to do is mention that I'm thinking of finally writing my memoirs, and you'd be surprised how fast the cheques come flooding in. Now, what is it you want me to do, Walker? Something frightfully nasty, no doubt."

"You were listening to my little chat with John Taylor."

"Well yes, but I can't honestly say it made much sense to me."
