Jane Harris had been a detective inspector for all of three weeks, and here she was standing in a garage with pools of blood at her feet.

Pools plural.

The cold, dead victim was called Raymond Masters. It was his garage. He cleaned cars for a living, or had done until about four hours ago. That was how long it had taken them to locate the source of the gunshots. A gun had been found in the dead man’s hand, and it had been fired. It wasn’t suicide, though. Two shots had been fired by Masters. One bullet had already been located, stuck in the wall to the left-hand side of the doors. One had done some damage to another human, if the bloodstains were to be believed. There were big dollops of the stuff. Masters had suffered a shot to the head. There should have been a spray of blood and brain matter, but cars had been parked here. Probably two of them, judging by the tyre marks.

Jane Harris had asked one of her team to look in Masters’ office. He would have bookings. She wanted to know which car or cars he had been working on. Maybe someone had wanted them. Cars got stolen all the time, didn’t they? But carjackers didn’t normally resort to guns. And why had the garage owner carried a gun of his own?

Her colleague Bob Sanders had a different theory. Bob had been on the force for almost as long as Jane had been alive. She trusted him when he mentioned the name George Renshaw.
