Thicker Than Water

I know because I asked every last one of them.’

‘Anything you could make out?’

‘One word, someti ~makmes. It sounds like “more” or “ma”. The rest is just gibberish.’

More? Ma?

‘Mark,’ I suggested.

Nurse Ryall nodded. ‘It could be that. Why?’

‘Because Kenny here -’ I pointed to the other bed ‘- had a stepson named Mark who died last year. Fell or jumped off a high building. And it hit Kenny hard - at least, according to some.’

Which explained nothing. I needed more than I had: needed a thread to follow through the maze, but Nurse Ryall had given me all she had. And she was well aware that I hadn’t returned the favour.

‘What is it?’ she demanded. ‘What is it really?’

‘Demonic possession,’ I said, deciding not to beat about the bush.

She gave a pained, incredulous laugh. ‘What, and you’d know?’

‘I’d know. I’ve seen it before.’

‘With two people? Two people at the same time -’ she groped for a phrase ‘- hooked up to each other like this?’

‘No,’ I admitted.

‘Well, then—’

‘Last time it was two hundred. The entire congregation of a church in West London. They all caught a dose of the same demon, and they all went out into the night to do unspeakable things to each other and to anyone else they met. I know about this shit, Charge Nurse Petra Ryall, because this shit is what I do for what I satirically call a living. They’re both possessed, and it’s one entity that’s possessing them. I don’t know what, and I don’t know why, but I might have a way of finding out. Is anyone else likely to come in here?’

She stared at me, her face a menagerie of misgivings. ‘At twelve. When the shift changes.’"

"‘Okay.’ I slid my hand into one of the paletot’s many inside pockets and took out my tin whistle. ‘Watch the door. If that cop makes a move, even if it’s just to scratch his arse, or if anyone else comes along, let me know. You’ll probably need to shake me or punch me in the shoulder or something. I may not hear you if you just whisper. Or even if you shout out.’

Nurse Ryall looked unconvinced, but she nodded.

I turned the chair beside Kenny’s bed to face me and sat down on it the wrong way round: there was no telling how long this would take, and if it dragged on it would be useful to have something to rest my elbows on.

Nurse Ryall watched me with uneasy fascination. ‘You’re going to do an exorcism?’ she asked.

‘I’mƒt sina going to try,’ I said. Then I shut her out of my mind.

I started to play, random notes shaping themselves quickly into a sort of loose, aimless proto-tune. It was hard at first. It was only the lining of my lung that had been damaged, not the lung itself, but still the sharp pain whenever my chest muscles worked meant that everything cost me more effort than usual.

This part of the gig is like what bats and dolphins do: you throw out a sound and you wait for it to come back to you, subtly changed as it bounces off the world’s various bumps and hollows. And from those changes you work out what the place you’re in looks like: whether it’s high up or low down; what natural hazards there might be; what sort of company you’re keeping.

My death-sense rides the music as a wolf spider rides the wind, trailing a single thread of silk across a thousand miles of ocean. It doesn’t have any volition or direction - not at first - but the music takes it where it needs to go, and in return it shapes the music until the feedback loop that runs through my ears to my brain and on down to my fingers and my pumping lungs narrows and refines the formless feeling into something patterned, perfect, vivid - like hearing your own name softly spoken in a roomful of bellowed arguments.

This is the first stage of the exorcism ritual, known variously as the finding or the summoning. Sometimes it comes quickly, sometimes it’s agonisingly drawn-out, and sometimes it doesn’t come at all. Tonight it was slow but inexorable like the building of a huge wave that towered over me like a wall - a wall I was mirroring in sound, climbing the scale and letting the volume build at the same time.

‘Someone’s going to hear you,’ Nurse Ryall warned, but right then her voice was just another feature of the room that the music bounced off, briefly: a bubble in the flow.

There was something there: behind the room, behind the merely physical space in which I sat and the two wounded men lay. Something was looking in at us from a direction so strange and so nebulous that I couldn’t turn around to meet its gaze. All I could do was keep playing, feeling its contours in the steady rise and rise and rise of the tune. It was coming towards me, and it was coming into focus: a tenuous presence that brought its own echo with it, a shadow with a darker shadow attached.

Then the wave broke over me and the darkness was absolute.
