Homicide Detail.. a wealthy businessman has disappeared. And it’s up to Joe Friday to determine if its murder, or suicide.

Joe Friday and Ben Romero interview Miss Banner, a woman who leases her home from the missing man. What might she know about Mr Dillon and his friends? All the cops have to go on for now is a letter from his sister. In voiceover, Joe tells about the complicated task in researching missing persons.

More interviews, and a business associate reveals cash withdrawn from accounts, and hard feelings after the death of Dillon’s wife. Does it indicate suicide? Other sources help in tracking the latest whereabouts of Dillon. Friends had forwarded mail, but who was he staying with, if anyone? Could he just be on vacation?

A hot tip lands in Joe’s lap when a store clerk reports sales tickets made by Mrs Dillon, several weeks after his disappearance. The description fits Miss Banner. Signatures match as well. There’s still the problem of the missing Mr Dillon., but an interview with the Gardner may have just provided the cops with an answer.
