After con man Greg Moxley married Rhoda Lorton, he took her money and flew—only to have his plane crash. Years later, Rhoda weds millionaire scion Carl Montaine. But now Moxley has turned up alive and well…with plans to pocket the Montaine fortune—or else make Rhoda’s bigamy public. Desperate to protect the good name of Montaine, Rhoda seeks out Perry Mason. But before Mason can reel in Moxley, somebody murders the scheming blackmailer. In a case that abounds in lethal twists, Perry Mason suddenly finds himself on a collision course with a cold-blooded killer.
