A "bury the hatchet" party in a wealthy enclave north of San Diego, California, ends with a hatchet buried in the head of the hostess. Bishop Bone takes the case at the request of ex-client, Vivian, who is actually being blackmailed. She wants Bone to solve the case before the police can link her to the dead woman. A homeless man was seen lingering around the edges of the party and a ring of burglars was also active in the area at the time of the hostess's death. Suspects abound and Bone is forced to go undercover as a homeless person to find the truth, but before he can do that a second woman - also a party attendee - is found dead. Both women were involved in the recently resolved, very controversial campaign to rid the children's pool in La Jolla of seals. The victims were also substantial investors in a medical implant company founded by Vivian's ex-husband. Gone soon realizes there is a lot more to this matter than murder, but by then, he's already become the next target..
