Don't Look Behind You by Angela Johnson

A survivor of horrific childhood trauma and a plot to kill him, Cameron De La Valle is now a world-renowned classical pianist. When he meets his assistant for a business lunch, he has no idea the afternoon will end with her murder. They had ordered the same thing and he could not erase the nagging doubt that the poisoned food had been meant for him, but the police dismissed the idea. But when he starts receiving threats and begins to have a series of "accidents", he knows something is wrong. He will have to face his own physical and emotional challenges to search for the truth. Can he find out who is terrorizing him and putting those closest to him in mortal jeopardy before it is too late?
