Amateur Crook is a 1937 American romantic comedy film directed by Sam Katzman.

[1] The film is also known as Crooked But Dumb (in the United Kingdom) and Jewel Thief (American TV title).

Betsy Cummings takes a job as a secretary, using the alias “Mary Layton”, only to find that her Father is being cheated by his brokers, Crone and Jan Jaffin.

Jimmy Baxter, an honest but broke artist, hides her as a mannequin, and helps her get away, in a stolen car.

Out of luck and almost out of time, they all end up in front of a Justice of the Peace, who tries to fathom out the facts, and whether to jail the pair or marry them, before his dinner gets cold.
