Not Dead Enough (Detective Superintendent Roy Grace, 3)

On the night Brian Bishop murdered his wife he was 60 miles away, asleep. 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 clever liar? As Grace digs deeper behind the façade of the Bishops' outwardly respectable lives, it becomes clear that everything is not at all as it seemed.
