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 young Brighton socialite, Katie Bishop. Soon, Grace 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 starts to become clear that all is not at all as it first seemed. And then he digs just a little too far, and suddenly the fragile stability of his own troubled, private world is facing destruction. "Detective Superintendent Roy Grace is investigating the bizarre slaying of Katie Bishop, a member of Brighton's social elite. Her husband Brian appears to be in the clear - he was in another town at the time, sound asleep. But Grace begins to suspect the presence of a doppelganger: is someone else - almost identical to Bishop - involved in the crime? Grace's diligent exhuming of murky secrets soon demonstrates that the Bishops' outwardly settled lives had darker corners. And as Grace gets close to the truth, he finds - paradoxically - that it's his own beleaguered private life which is on the line."--Back cover.
