The Backs, as they called it, was a straight passage running along the rear of the terraced houses on Atkinson Row. It was little more than an access road; though narrow and unevenly cobbled, it was barely wide enough for vehicles, which meant that whoever had left this one here would be causing a massive obstruction – and right on the other side of the gate to No. 8. Harry wasn’t even sure if he’d be able to get out there. He had no clue who the vehicle might belong to, though he had a notion that the Rodwells, the young couple next door, were a bit rum. Okay, they weren’t lowlifes – they were teachers, apparently – but they’d had more than a few noisy barbecues in their garden during the summer months, which had gone on until late, and which they’d never offered apologies for. Even when they weren’t having barbecues, their friends tended to come and go loudly. A couple of times, he’d heard the Rodwells themselves squabbling through the dividing wall between his bedroom and theirs. So it wouldn’t be unlike them, or someone they knew, to have thoughtlessly left a vehicle in such an inconvenient place.

Grumpily, all previous concerns forgotten – because one thing you could never do was challenge Harry Hopkins in his own home – he unlocked the back door and stepped out. The garden light came on, and there was no mistake: a large, dark vehicle was parked just the other side of his back wall. He stumped along the path, Milly trotting inquisitively behind him, undid the bolts and yanked the gate open – to find a vehicle there so large that it literally filled the alley. Though its rear end was close to his gate, perhaps a yard to his left, there was minimal room to manoeuvre; less than a foot’s clearance separated its offside flank from his wall, which meant that he could only move along it if he slithered sideways.

But none of that mattered as much as the kind of vehicle it was.

A van.

A black transit van.

Fleeting pinpricks of sweat appeared on Harry’s brow; it was several seconds before he could even engage his voice.

‘Okay … okay,’ he grunted to himself.

This was a challenge, and no mistake – but there was no need to get jumpy. He’d already worked out what the problem was here: the Rodwells and their inconsiderate friends.
