The night that Brian Bishop murdered his wife, he was sixty miles away, asleep in bed. At least, that's the way it looks to Detective Superintendent Roy Grace who is called in to investigate the case involving the kinky slaying of the beautiful young Brighton socialite, Katie bishop. Grace begins to come to the conclusion that her husband has performed the impossible, the feat of being in two places at once. Either that or someone has stolen his ID. The other possibility being that he is the best liar Grace has ever come across. However as Grace starts to get his teeth into the case it becomes clear that the Bishops' outwardly respectable lives were not all they seemed to be. But Grace makes the mistake of digging just that little bit too deeply and suddenly his own troubled, private world is facing destruction.
