Just under an hour later, he was in his car and heading for his home in Oxgangs. There was a supermarket almost on his doorstep, and he stopped long enough to grab a microwave curry and a bottle of Appletiser, plus the evening paper. The story on the front page concerned a drug dealer who had just been found guilty and sent to jail. Fox knew the detective who had led the inquiry – he’d been the subject of a Complaints investigation two years back. Now he was smiling for the cameras, job done.

How come you hate cops so much? The question Scholes had asked. Time was, CID could cut corners and be sure of getting away with it. Fox’s task was to stop them doing that. Not for ever and a day – in a year or two he would be back in CID himself, rubbing shoulders with those he had scrutinised; trying to put drug dealers behind bars without bending the rules, fearful of the Complaints and coming to despise them. He had begun to wonder if he could do that – work with officers who knew his past; work what everyone regarded as ‘proper’ cases…

He stuffed the newspaper into the bottom of his basket, covered by his other purchases.

The bungalow was in darkness. He’d thought of buying one of those timers that brought a light on at dusk, but knew this was no real deterrent to housebreakers. He had little enough worth stealing: TV and computer, after which they’d be looking around in vain. A couple of homes near him had been broken into in the past month. He’d even had a police constable on his doorstep, asking if he’d seen or heard anything. Fox hadn’t bothered identifying himself as a fellow officer. He’d just shaken his head and the constable had nodded and headed elsewhere.
