One of those morning interviews, then, when the interviewee’s time isn’t particularly important and there are unending minutes to fill. Slightly informative noise had to be created to cover the real interest, the pictures. Not the helicopter any more: footage from the ground, also shot before dawn, of fire crews directing inadequate-looking streams of water into a pulsing orange hell, the ground a reflecting pool in which coiled hoses wallowed.

My can was half empty already, its comforting weight gone, its top warm. I returned to the kitchen and topped it up from the one-third-full can I had found behind the lamp. Waste not, want not. The coldness and fizz of the remaining half of the fresh lager would take care of the flatness and warmth of the older stuff. But as a precaution, I poured it through a metal tea-strainer I kept beside the sink. In the past there had been instances when I had watched, horrified, as a glob of mould had slipped from a too-far-gone can into perfectly good beer. It was heartbreaking to have to pour it all down the sink. And there had been times when I had not washed it away, and they were even worse. But the strainer, found in a charity shop, had been a useful investment. This time nothing was intercepted, and the found beer frothed in a reassuring way. I had three cans in the fridge. That would probably do me for the morning.

‘Chances of a serious reaction are one in a million, one in 10 million really,’ the television voice was saying.

‘Ten million people in London,’ I said to the TV, ‘so one poor bastard …’

I tried to drink from the refilled can, but misaligned the aperture with my mouth, dribbling beer down the front of my T-shirt.

‘Shit.’

I ran the back of my wrist across my chin. The drilling, which had paused for breath, chose that moment to resume. I hated the pauses in the drilling more than anything, because they invited the thought that the noise might have stopped for good, which was seldom the case. The builders on the other side were now making their own contribution: a hammer-blow, perhaps metal against metal, which repeated eight or nine times, then stopped, then started again. Through the flat, from the direction of the street, came the throat-clearing sound of a diesel engine and a steady rattle of machinery.

I threw the tree an angry glance. It was planted in next door’s back garden, another of their multiple insults. Through the splattered glass of the kitchen ceiling, I saw a flash of white in its black limbs.

A cockatoo, sitting in the tree, looking down at me.

No, not possible.

I changed my position to get a better view through one of the cleaner patches of grimy glass. The white shape ducked from view. I stepped back. There it was again – not a cockatoo, but a white plastic bag caught in the branches.
