Not Dead Enough by James, Peter (2007) Hardcover

On the night Brian Bishop murdered his wife he was sixty miles away, asleep in bed at the time. At least that's the way it looks to Detective Superintendent Roy Grace, who is called in to investigate the kinky slaying of beautiful socialite, Katie Bishop. Grace soon starts coming to the conclusion that Bishop has performed the apparently impossible feat of being in two places at once. Has someone stolen his identity or is he simply a very clever liar? As Grace digs deeper behind the facade of the Bishops' outwardly respectable lives, it becomes clear that everything is not at all as it first seemed. Then he digs just a little too far, and suddenly the fragile stability of his own troubled, private world is facing destruction ...'Packed with sharp dialogue, an appealing cast and vivid cameos of the more sinister face of Brighton' The Times 'Very accomplished...I loved it' Observer
