I caught a lift in the local area car down to Swiss Cottage tube and hopped a Jubilee Line train into town. I doubted that Lady Ty had the manpower or the inclination to have the stations covered, and one of the few advantages of blowing out my phone was that it couldn’t be jacked, ditto any trackers she might have stashed about my person. I’m not being paranoid, you know. You can buy those things off the internet.
Rush hour was almost in full flood when I got on the train, and the carriage was crowded just short of the transition between the willing suspension of personal space and packed in like sardines. I spotted some of the passengers eyeing me up as I took a position at the end of the carriage with my back to the connecting door. I was sending out mixed signals, the suit and reassuring countenance of my face going one way, the fact that I’d obviously been in a fight recently and was mixed race going the other. It’s a myth that Londoners are oblivious to one another on the tube: we’re hyper-aware of each other and are constantly revising our what-if scenarios and counter strategies. What if that suavely handsome yet ethnic young man asks me for money? Do I give or refuse? If he makes a joke do I respond, and if so will it be a shy smile or a guffaw? If he’s been hurt in a fight does he need help? If I help him will I find myself drawn into a threatening situation, or an adventure, or a wild interracial romance? Will I miss supper? If he opens his jacket and yells ‘God is great’， will I make it down the other end of the carriage in time?
All the time most of us were devising friction-free strategies to promote peace in our time, our carriage and please God at least until I get home. It’s called, by people over sixty, common courtesy, and its purpose is to stop us from killing each other. It was like vestigia: you weren’t always aware of them but you instinctively shaped your behaviour in response to the accumulation of magic around you. This is what kept ghosts going, I realised; they lived off the vestigia like LEDs off a long-life battery, powering down to ration it out. I remembered the dead space that was the vampire house in Purley. According to Nightingale, vampires were ordinary people who became ‘infected’， no one was sure how or why, and started feeding off the magic potential, including the vestigia, of their surroundings.
‘But it’s not enough to sustain a living being,’ Nightingale had said. ‘So they go hunting for more magic.’ The best source of that, according to Isaac Newton, was human beings, but you can’t steal magic from a person, or any life more complex than slime moulds, except at the point of death and even then it isn’t easy. I’d asked the obvious question – why the blood-drinking? He said that nobody knew. I asked him why hadn’t anyone done any experiments, and he gave me a strange look.
‘There were some experiments done,’ he’d said after a long pause. ‘During the war. But the results were considered unethical and the files were sealed.’
‘We were going to use vampires during the war?’ I’d asked, and been surprised by the look of genuine hurt and anger on Nightingale’s face. ‘No,’ he’d said sharply, and then, with more moderation, ‘Not us – the Germans.’
Sometimes when someone tells you not to go somewhere it’s better not to go there.
The genii locorum, like Beverley, Oxley and the rest of the dysfunctional Thames family, were also living beings on one level, and also got their power from their surroundings. Bartholomew and Polidori both suggested that they drew sustenance from all the diverse and myriad life and magic within their domains. I was sceptical, but I was willing to accept that they lived in symbiosis with their ‘domains’， whereas vampires were clearly parasitical. What if that was mirrored by ghosts? If Thomas Wallpenny was in some way part of the vestigia he inhabited and drew power from, a symbiont, then the revenant could be a parasite, a ghost vampire. That would explain the shrunken cauliflower brains of the victims – they’d had the magic sucked out of them.
Which meant that the summoning I’d done with the calculators had achieved nothing more than to feed Henry Pyke’s appetite for magic. But I also wondered if you couldn’t attract a revenant by spilling magic around like laying a chum line for shark. By the time the train pulled into Baker Street, I was already beginning to formulate a plan.
The tube is a good place for this sort of conceptual breakthrough because, unless you’ve got something to read, there’s bugger all else to do.
This time when I arrived at Westminster Mortuary I didn’t even have to show my warrant card. The guards on the gate just waved me through. Nightingale was waiting for me in the locker room. While I was kitting out, I gave him a brief explanation of my meeting with Tyburn.
