Rivers of London - Ben Aaronovitch [60]
We sat down on opposite sides of the lab bench and Nightingale placed an object between us. It was a small apple. ‘Impello,’ he said, and the apple rose into the air. It hung there, rotating slowly, while I checked for wires, rods and anything else I could think of. I poked it with my finger, but it felt like it was embedded in something solid.
‘Seen enough?’
I nodded, and Nightingale brought out a basket of apples – a wicker basket with a handle and a check napkin, no less. He placed a second apple in front of me, and I didn’t need him to explain the next step. He levitated the apple, I listened for the forma, concentrated on my own apple and said, ‘Impello.’
I wasn’t really that surprised when nothing happened.
‘It does get easier,’ said Nightingale. ‘It’s just that it gets easier slowly.’
I looked at the basket. ‘Why do we have so many apples?’
‘They have a tendency to explode,’ said Nightingale.
The next morning I went out and bought three sets of eye protectors and a heavy-duty lab apron. Nightingale hadn’t been kidding about the exploding fruit, and I’d spent the afternoon smelling of apple juice and the evening picking pips out of my clothing. I asked Nightingale why we didn’t train with something more durable like ball bearings, but he said that magic required the mastery of fine control right from the start.
‘Young men are always tempted to use brute force,’ Nightingale had said. ‘It’s like learning to shoot a rifle: because it’s inherently dangerous you teach safety, accuracy and speed – in that order.’
We went through a lot of apples in that first session. I was getting them in the air but sooner or later – splat! There was a brief phase when it was fun and then it got boring. After a week of practice, I could levitate an apple without it exploding nine times out of ten. I wasn’t a happy little wizard, though.
What worried me was where the power was coming from. I never was very good at electricity, so I didn’t know how much power it took to make a werelight. But levitating one small apple against the earth’s gravity – that was essentially the standard definition of one newton of force, and it should be using one theoretical joule of energy every second. The laws of thermodynamics are pretty strict about this sort of thing, and they say that you never get something for nothing. Which meant that that joule was coming from somewhere – but from where? From my brain?
‘So it’s like ESP,’ said Lesley during one of herperiodic visits to the coach house. Officially she was there to liaise with me on the case, but really she was there for the wide-screen TV, takeaways and the unresolved sexual tension. Besides, apart from a couple of unconfirmed cases around the same time as the Neal Street attack, nothing had come to our attention.
‘Like that guy on that show who could move things around,’ she said.
‘It doesn’t feel like I’m moving things around with my mind,’ I said. ‘It’s like I’m making shapes with my mind, which affects something else, which makes stuff happen at the other end. Do you know what a theremin is?’
‘It’s that weirdo sci-fi musical instrument with the loops,’ she said. ‘Right?’
‘Pretty much,’ I said. ‘The point is, it’s the only musical instrument you don’t physically touch. You make shapes with your hands and you get a sound. The shapes are completely abstract, so you have to learn to associate a particular shape with a note and tone before you can get the thing to make a tune.’
‘What does Nightingale say?’
‘He says that if I stopped letting myself get distracted I might spend less time covered in bits of apple.’
At the end of March, the clocks go forward one hour to mark the start of British Summer Time. I woke up late to find
