CIPHER BUREAU

- This spy thriller is centered upon the actions of the Cipher Bureau, a part of a government agency devoted to intercepting and decoding secret messages. The protagonist must destroy a ring of thinly disguised German spies. The film contains a lot of interesting information about how codes are deciphered and other things such as the ways that broadcast music can contain secret codes. The spies on both sides get involved in a gun battle.

PANAMA PATROL

- This sequel to Grand National's 1938 actioner Cipher Bureau once again stars Leon Ames as bureau head Major Philip Waring. In case you're wondering, the Cipher Bureau is a government agency in charge of decoding enemy messages. Teamed with agent Helen Lane (Charlotte Wynters), Major Waring is dispatched to the Panama Canal. Here the two operatives discover that an Oriental spy ring (no nationalities, please: this is still 1939) is stealing vital secrets concerning the Canal. Almost as dangerous as the spies is Abner Biberman in the role of a turncoat bureau agent. The very brief "Cipher Bureau" series was created by Arthur Hoerl and Monroe Sheff.
