Detective Carter McLean is the sole survivor of a plane crash that claimed the lives of his four best friends. He returns to work, but is haunted by guilt and horrific memories. Therefore, he decides to complete something for each of his friends that they left unfinished. Additionally, he is investigating a case involving the disappearance of one of those friends' wives eighteen months before the crash. On top of that, his boss's daughter has a stalker. The only person Carter can confide in is Sergeant Evans. But even she begins to doubt whether he can handle it and whether he is losing his mind. Detectives Rowan Jackman and Marie Evans are once again faced with three mysteries and, above all, concerns about whether they can truly trust their friend and colleague Carter... The fourth friend will delight readers of Angela Marsons and Patricia Gibney.
