The German The Squeaker is the third film version of the Edgar Wallace mystery novel of the same name. The title character is an omnipotent "fence" who has cornered the diamond-smuggling racket. The fence travels in polite society under the guise of a wealthy philanthropist. A Scotland Yard detective pretends to be an ex-convict in order to infiltrate the Squeaker's gang and to track down the stolen gems. The Squeaker was one of several German Edgar Wallace adaptations of the 1960s, ground out simultaneously with Britain's long-running Wallace B-picture series. ~ Hal Erickson, Rovi
