A storekeeper has been robbed and killed by two thieves, who have also wounded a police officer. The wife of the unfortunate storekeeper provides Friday (Jack Webb) and Smith (Ben Alexander) with a vital clue: one of the thieves kept an unfolded handkerchief in his breast pocket. As often happens on this series, the perp's sloppiness proves to be his undoing. This episode was adapted from the Dragnet radio broadcast of June 22, 1954. ~ Hal Erickson, Rovi
