"Shut up," I said.

"Aren't you going to introduce me to your new friends, John?" said Bad Penny, spreading her smile generously around her.

I raised an eyebrow. "Walker didn't brief you? Or haven't you reported in recently? You always were slack when it came to doing the research on a case. Well, this is Sinner, and his girl-fiend Pretty Poison, and that is Madman. We've just destroyed the Lamentation."

"Oh dear," said Bad Penny. "How sad. Fallen in with bad company again, I see. What am I going to do with you, John? I know! I'll kill you right here and now. And just to keep everything neat and tidy, your friends can die with you." She turned her powerful smile on Sinner. "You disapprove of John, don't you? How sweet. Perhaps you'd like to break his neck for me? I'd really like that. In fact, I'd like it if you all beat each other to death, right in front of me."

And just like that, she was suddenly the most attractive woman in the world. Her sexuality blazed like someone had just opened a furnace door. Her presence filled the street, impossible to look away from, impossible to resist. To see her was to want her, to need her, more than life itself. I had my gift, and Bad Penny had hers. She had become the woman you'd do anything for, including murder. Her greatest weapon had always been herself. No-one could resist her body, once she'd turned it up to eleven. Except... for all our special abilities, Sinner and Madman and I were just men, while Pretty Poison was a demon succubus from Hell.

"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.
