The empty empties I crushed and put in the recycling; the part-empties I left by the sink. Then I sat on the sofa. The drilling had not stopped, or even subsided, but I had a little insulation in my head now, and it was at the other end of the flat. And only on the one side, for now. I felt pretty good, relatively. The meeting with Pierce was set for eleven, a civilised time, and I wasn’t expected in the office until Thursday. That was an aeon away. All that mattered was not screwing up the Pierce interview – and I was unusually well-prepared. I had actually read Pierce’s books and many of his articles; that was the reason I wanted to interview him in the first place. I just had to focus and stick to it for a couple of days, and the Polly-threat might recede, give me some time and space to get my head together, to make some changes, stabilise things.

‘Getting myself back on track, yes indeed,’ I said to the tree. ‘What do you have to say about that? Two interviews today, and they’re both going to go great.’

It had nothing to say about that.

The TV and DVD player were on standby, not completely off; they had done this themselves during the night. So discreet, so obliging. I turned the TV on and switched to the news. London Blaze, said the red caption beside the crawl.

‘… real concern isn’t the fuel but some of the additives used in some of these related processes, which we understand were on the site.’ Not a newsreader voice but the unpolished, hesitant voice of an expert, speaking over pre-dawn helicopter footage of the fire, hungry orange squirts of flame, the smoke column like a thick black neck attached to a head that was buried in the ground, swallowing, chewing, consuming. Around it, a necklace of twinkling blue lights.

‘So just how concerned should we be?’ The interviewer, a female voice, cut in. I liked this question. I wanted to precisely calibrate my concern.

‘Well, as I say,’ the interviewee, a male voice, said, ‘it’s not really a question of the fuel but the other chemicals that may have been present; now we don’t know what these were exactly, not as yet, but we understand there were substantial quantities of material on the site, and some of these can be, well, you wouldn’t want to put them on your cornflakes, ha ha, but still the question as always is one of quantifying risk.’
