When a woman appears on Private Investigator Harry Bennett’s doorstep, alleging to be his sister, he questions her story. The stranger resembles his mother, but if he had a sister, wouldn’t he remember her? 

A photo album found in a family storage locker holds the only clue: a picture taken shortly before the car crash that killed his parents. The photo shows a solemn eight-year-old Harry, his parents, and a baby in a christening gown. 

Harry turns to the one person with knowledge of his past, a woman who treated him like a son, but before he can uncover the truth, she is murdered.

As Harry chases an elusive killer, seeks the identity of his supposed sister, and struggles to unlock his memories, family secrets come to light, forever altering Harry’s view of the past and casting shadows over his future.
