Brad Parker and Karen Richmond Medical Thrillers Betrayal of Trust

Who's killing the cancer researchers?A leading clinical investigator is butchered in his hotel room hours after receiving a prestigious award for cancer research. Weeks later, a second researcher is the victim of an apparently random mugging in a parking garage. Unexpectedly, crime scene DNA establishes that the two men were killed by the same woman. But her identity remains unknown, her motive is mysterious, and the connections between the victims are scant-except that they were both collaborating with Professor Brad Parker at the Maine Translational Research Institute. When the killer strikes close to home, Brad and his fiancée-state police lieutenant Karen Richmond-are drawn into a nightmare of maniacal revenge. Until Brad sets a trap for the killer...or falls prey to a trap the killer has set for him.
