Synopsis:
When Flash returns home after an adventure, he finds Fred Dallman waiting in his apartment. Dallman explains that he has embezzled money from his bank and that another man, David Dean, was convicted of the crime. Dean was sent to prison and is now a hostage held by escaped convicts. After Dallman finishes his story, he disappears.

Flash races to Arizona City where the jail break occurred. He finds and rescues Dean, who explains that his brother Jack is also in trouble. Flash protects Jack, who is being recruited by some hoodlums. Then Flash seaches for Dallman. Flash learns that Dallman died in a car crash before he confessed in Barry's apartment. Flash finds the money and clears Dean, but he remains puzzled by the after-death appearance of Dallman.
