Fire and Ice by J.A. Jance

J.P. Beaumont and his wife Mel Soames have been working on finding the person who's been burning women to death in western Washington. When the latest body is found with the victim's teeth still intact, Beaumont and the state's special homicide team hope this will provide them with a lead since the other victims are still unidentified. Meanwhile, in Arizona, Sheriff Joanna Brady and her colleagues are working on the murder of a man who was run over repeatedly in some dunes. Over time, as Beaumont and Joanna delve into their separate cases, information surfaces that indicates the two are connected. Will they be able to put their past attraction aside to bring the people responsible to justice? In Fire and Ice, Jance reunites her two popular series characters. This is their second appearance together, after Partner in Crime. I really love the J.P. Beaumont series and enjoyed this latest mystery.
