The Saint uncovers a Nazi Spy Ring operating out of Florida.
One of Patricia Holm's friends sends an invitation for Patricia and her friend, Simon Templar to visit Miami. Upon arrival, however, The Saint and Patricia discover Pat's friend and her husband are nowhere to be found. They take up residence in the friend's house. A few days later, a tanker explodes off the Florida coast and Simon discovers the dead body of a sailor washed up on shore. Attached to the wrist of the body is a lifebelt from the British submarine H.M.S. Triton. Simon suspects a link between the disappearance of Patricia's friends, the explosion, and a millionaire yachtsman named Randolph March. March's yacht is moored not far from the explosion, and Templar launch the investigation by climbing aboard the yacht, leaving the sailor's corpse in a stateroom for the police to find, and challenging March to give up his secrets.
