Synopsis by Sandra Brennan
Following a string of mysterious robberies, Scotland Yard assigns its best detective, Inspector Elk, to bring the crooks to justice. The only clue the villains leave at the crime scene is a rendering of a frog. Still that is enough for intrepid Elk to solve the case, but not after considerable danger, excitement and comedy. This is the sequel to 1937's The Frog.
