A brutal murder in the operating suite of an exclusive Beverly Hills hospital is investigated by obstetrician Hannah Kline and her recent lover, Los Angeles police detective Daniel Ross. The couple are taking a well-earned, romantic vacation when their idyll is disrupted by an encounter with Dr. Wesley Templeton, Beverly Hills plastic surgeon, and ex-husband of Hannah’s college roommate Sara. Two weeks later, Templeton is found murdered at West Beverly Hospital. Everyone with opportunity appears to have no motive, and the long list of people with motives, lack opportunity. Sara is definitely on the suspect list, but Hannah knows her old friend isn’t capable of murder and decides to do some investigating on her own. In the meantime, an increasingly desperate killer is killing again, and again.
