To his friends and enemies alike, it looks as though Tom Thorne's career is on the skids. Depressed by the recent loss of his father and berated for seriously overstepping the mark on his last case, he's been encouraged to take gardening leave. For an ambitious detective, especially one without so much as a window box, it's a fairly dire situation. But when three homeless men are murdered, Thorne is seconded to the streets. Not as a policeman on the beat, but as one of life's rejects. Thorne discovers the horrifying link between the homeless victims and the perpetrators of a fifteen-year-old atrocity. The word on the street is that the killer is a cop. This is the fifth Tom Thorne-book.
