After we crossed Father Thames at Vauxhall I got the cabbie to fork right onto Millbank, where New Labour used to keep shop in the good old days before they availed themselves - with no sense of irony - of the cheaper work-force available in North Shields. There were lights on in the decaying tower block, shining pale and a little baleful across the restless night: the ghosts of Tony Blair and Gordon Brown, maybe, pursuing their old disagreements like the boarhound and the boar through the rifts of some low-rent eternity.

The cab dropped me off at the western end of the Strand, near Cockspur Street. There was eighteen quid on the clock and the cabbie took the twenty with bad grace, no doubt believing that a pick-up in Brixton at that hour of the morning deserved something special in the way of a tip. I was inclined to agree, but that was all I had on me so the argument was purely academic. He muttered something under his breath as he drove away: probably, in the circumstances, something more or less accurate.

The walk from the centre of town back up to Turnpike Lane took me over an hour. I felt like I needed the time to think, even if my thoughts kept circling around the same drain. Asmodeus had killed Ginny, and then he’d hung around the scene long enough to pick up my scent and take a crack at me. What the Hell was he up to? We’d had a sort of love-hate thing going for most of the time Rafi was at the Stanger. Asmodeus knew who he had to thank for his human ball and chain, and would have liked nothing better than to rip my head off and spit down my throat. But he knew that killing me would close a possible escape route, so for the most part he contented himself with more subtle forms of revenge. The only time he’d ever seriously tried to kill me was when he was sure Fanke’s satanists were going to cut him loose again with a ritual involving human sacrifice.

Was that the link? Ginny. Fanke. The Satanist Church. Was Asmodeus demob-happy again, looking for an early remission on his life sentence? Or had he just given up hoping that I’d find a musical sieve that would strain out the demon from the man? Either way, it was bad news for me.

In Somers Town I passed a small group of zombies sitting huddled around a fire they’d made in the eternally closed doorway of an abandoned parking garage. It was a pathetic sight, because there was no way the fire could warm them: the nerves in the dermal layers of the skin are the first to go. And the night was still clinging onto the day’s heat like a lover keen for one last sweaty embrace, so surely this was the only campfire burning in London tonight. Comfort food for the dead.
