Imperfection is a new crime series featuring D.I. Stewart Gardener and D. S. Sean Reilly, and set in the West Yorkshire city of Leeds. A haunting message scrawled on the dressing room wall of a theatre: the scene of a murder. It had been written using the blood from the victim, previously drained in a separate location. At the autopsy, D.I. Gardener and D.S. Reilly are shown a riddle carved into the chest of the corpse, informing them there would be more. Their efforts to find out why are continually blocked by a wall of contradiction, with little in the way of evidence to support their cause. Steered back to the scene of the crime and a disused prop room, Gardener and his trusted sergeant find another puzzle. The murderer, it seems, is playing games. It soon becomes clear to Gardener and Reilly that to find the killer they need to solve the clues, and to do that, they must tunnel their way into the past, where the streets were paved with gold, and to a man who had terrified people before either of them had even been born...
