Tana French's debut of the Dublin Murder Squad series. In the summer of 1984, the police are called to search for three children who didn't come home when called. They find only one, wearing blood-filled sneakers, terrorized and unable to remember anything about the day. In 2004, that child, Rob Ryan, is a detective who keeps quiet about his past. The only one who knows is his partner and best friend, Cassie Maddox. Now they are investigating the murder of a 12- year old girl found in the same wood with haunting similarities to the old case. Ryan has only bits of memory, but feels he may be able to solve this case and that of his own past.
