 McGee is drawn away from his usual haunt of Florida by a job offer from Mona Yeoman, who suspects that her estranged husband has stolen from her considerable trust fund. Before the investigation begins, Mona is murdered before McGee's eyes by an unseen gunman. By the time he summons the police to the scene, her body has disappeared. McGee then sets out to solve her murder.
