Lieutenant Lucas Davenport is determined to track down a diabolically clever serial killer who leads a double life, carefully picks out his female victims, and taunts the police with notes signed "Maddog."

Lucas Davenport's old boss, Rose Marie Roux, has moved up and taken Lucas with her, creating for him a special troubleshooting job for the cases that are too complicated for others to handle--cases like when two people, a white woman and a black man, are found hanging naked from a tree in the woods of northern Minnesota.

A wealthy federal judge, there's no short list of people who could have a vendetta against Sands, but the gruesome murders, especially that of his children, turn their St. Paul community on its head.
