A man lacking identification and unable to speak is found semiconscious on a British beach and immediately draws national press as Mr. Nobody. But when neuropsychiatrist Dr. Emma Lewis is invited to assess him, she discovers he does recall something about her own past that no one else knows.
The man knows the details of Emma’s childhood and makes her think he was her dad or was sent by her dad. He didn’t–he had just researched her. Ever since he was a kid he would suddenly black out and regain consciousness with no memory. Emma had written a paper on his case, so he wanted to find her and get treated by her. He left himself clues between each reset. He confessed his murders to Emma, and then tried to kill her but fell out a window and died. Emma kept his secret and said he killed himself.
