Since the disbanding of the Special Homicide Investigation Team, JP Beaumont's biggest concern is pondering whether he and his wife, Mel, should finally get a dog. But one voicemail from his old friend Ralph Ames is about to change that. Through Ralph, Beau has become involved in an organization called The Last Chance, which enlists a number of retired homicide investigators to tackle long unsolved cold cases. The one that has just landed on Beau's plate is a 30-year-old missing person case. The facts are muddy at best; Janice Marie Harrison's car was found abandoned near a bridge, and scratched in the dirt nearby was the word 'sorry'. It's possible her death was a suicide, but her body was never found. And as Beau begins to investigate, he discovers that no one connected to Janice is exactly what they seem. The question is, which of them knows the truth? And why have they kept it buried?
