The subject didn’t pass. The subject walked in and stood behind him at the counter. In a panic, Dirk ordered a tuna and sweetcorn roll, which he hated, and a cappuccino, which went particularly badly with fish, and hurried off to sit at one of the small tables. He wanted to be able to bury himself in a newspaper, but he didn’t have one, so he had to make do with his post. He pored over it intently. Various bills of the usual preposterous and wildly overoptimistic kind. Various circulars of the strange type that private detectives tended to receive—catalogues full of tiny electronic gadgets all designed to counteract each other; ads for peculiar grades of film or revolutionary new types of thin plastic strips. Dirk couldn’t be bothered with any of it, though he did pause for a moment over a flyer for a newly published book on advanced surveillance techniques. He screwed it up crossly and threw it on the floor.

The last envelope was another bank statement. His bank had long ago got into the habit of sending them to him on a weekly basis, just to make the point, really. They hadn’t yet adjusted to his new sheen of solvency, or didn’t trust it. Probably hadn’t even noticed it, in fact. He opened the statement, still only half-believing.

Yes.

Another £3,253.29. Last Friday. Incredible. Inexplicable. But there.

There was also something else odd, though. It took him a moment or two to spot it, because he was keeping half an eye expertly trained on his subject, who was buying coffee and a doughnut and paying for it out of a fan of twenties.

The last entry on Dirk’s statement was for a cash withdrawal on his debit card: £500. Yesterday. The statement had obviously been sent out at close of business yesterday, and it had the day’s transactions up to date. That was all very excellent and efficient and a fine testimony to the efficacy of modern computer technology, of course, but the fact was that Dirk hadn’t withdrawn £500 yesterday, or any other day for that matter. His card must have been stolen. Hell’s bells! He fished anxiously for his wallet.

No. His cards were there. Safe.

He thought about it. He couldn’t envisage any way in which a fraudster could make an actual cash withdrawal without the actual card. A horrible clammy thought suddenly grabbed his stomach. These were his own bank statements he’d been getting, weren’t they? He checked in alarm. Yes. His name, his address, his account number. He had double-checked the other ones last night, several times. Definitely his statements. They just didn’t seem to be his financial transactions, that was all.

Time to concentrate on the job in hand. He looked up. His quarry was sitting two tables away, patiently munching his bun and staring into the middle distance.
