Bart Regan next assignment starts when he is told about the threat from smuggling fifth columnists into the country through Florida from South America. He is told an agent named Powers had looked into it but was found dead. A second agent named Conover was missing. Suddenly the missing agent walks into the office mumbling about finding nothing but goldfish. He says he hates goldfish. And that he sees one floating in the air. And then he follows that vision out the window of the tall building. A strange case indeed.
