In Blood Work, Connelly introduces a new character, Terry McCaleb, who was a top man at the FBI until a heart ailment forced his early retirement. Now he lives a quiet life, nursing his new heart and restoring the boat on which he lives in Los Angeles Harbor. Although he isn't looking for any excitement, when Graciela Rivers asks him to investigate her sister Gloria's death, her story hooks him immediately: the new heart beating in McCaleb's chest is Gloria's.
When a sheriff's detective shows up on former FBI man Terry McCaleb's Catalina Island doorstep and requests his help in analyzing photographs of a crime scene, McCaleb at first demurs. He's newly married (to Graciela, who herself dragged him from retirement into a case in Blood Work), has a new baby daughter, and is finally strong again after a heart transplant. But once a bloodhound, always a bloodhound.
