The motive

Summary: Success has its disadvantages. Abe Glitzky, once a homicide cop and now a high-level administrator in the San Francisco Police Department, is none too thrilled to be called upon by the mayor, his longtime friend Kathy West, to help investigate a case. Both Paul Hanover, a wealthy businessman and significant contributor to West's campaign coffers, and a woman were found dead in Hanover's home, and the fire that leveled the house wasn't the cause: both victims died of gunshot wounds. Although it looks like a "clean" murder-suicide, forensics proves otherwise, much to the mayor's relief. But now there's a double-homicide to solve. Normally, Glitzky wouldn't mind helping out his old department, but the lead investigator on the case is Dan Cuneo, someone Glitzky, along with his friend, attorney Dismas "Diz" Hardy, had locked horns with some time ago. The likelihood of Glitzky and Cuneo working together amicably is remote, especially when it turns out that the chief suspect is Diz's ex-girlfriend.
