‘Drops. Big drops. Here. Mi foot skidded and I slipped. And I just got up and kept running.’

‘Did you tell the police about the drops of water?’

‘No. I forgot. Till now. I forgot.’

Something that had bothered Strike all along had at last been made clear. He let out a great satisfied sigh and grinned. The other two stared.

The weekend stretched ahead, warm and empty. Strike sat at his open window again, smoking and watching the hordes of shoppers passing along Denmark Street, the case report open on his lap, the police file on the desk, making a list for himself of points still to be clarified, and sifting the morass of information he had collected.

For a while he contemplated a photograph of the front of number 18 as it had been on the morning after Lula died. There was a small, but to Strike significant, difference between the frontage as it had been then, and as it was now. From time to time he moved to the computer; once to find out the agent who represented Deeby Macc; then to look at the share price for Albris. His notebook lay open beside him at a page full of truncated sentences and questions, all in his dense, spiky handwriting. When his mobile rang, he raised it to his ear without checking who was on the other end.

‘Ah, Mr Strike,’ said Peter Gillespie’s voice. ‘How nice of you to pick up.’

‘Oh, hello, Peter,’ said Strike. ‘Got you working weekends now, has he?’

‘Some of us have no option but to work at weekends. You haven’t returned any of my weekday phone calls.’

‘I’ve been busy. Working.’

‘I see. Does that mean we can expect a repayment soon?’

‘I expect so.’

‘You expect so?’

‘Yeah,’ said Strike. ‘I should be in a position to give you something in the next few weeks.’

‘Mr Strike, your attitude astounds me. You undertook to repay Mr Rokeby monthly, and you are now in arrears to the tune of—’

‘I can’t pay you what I haven’t got. If you hold tight, I should be able to give you all of it back. Maybe even in a oner.’

‘I’m afraid that simply isn’t good enough. Unless you bring these repayments up to date—’

‘Gillespie,’ said Strike, his eyes on the bright sky beyond the window, ‘we both know old Jonny isn’t going to sue his one-legged war-hero son for repayment of a loan that wouldn’t keep his butler in fucking bath salts. I’ll give him back his money, with interest, within the next couple of months, and he can stick it up his arse and set fire to it, if he likes. Tell him that, from me, and now get off my fucking back.’

Strike hung up, interested to note that he had not really lost his temper at all, but still felt mildly cheerful.
