This Universal wartime quickie was one of the nonhorror titles included in the SHOCK! package issued to television in the late 1950s, viewed less frequently as the years have passed. Directed in brisk fashion by serial specialist Ray Taylor, the setting is China circa 1940-41, before the Japanese attack on Pearl Harbor. German Karl Renner (Felix Basch) possesses a secret note showing the whereabouts of a cache of jewels designed to help the Chinese fight against Japan; among those seeking the hidden treasure are Elena Varnoff (Irene Hervey), Renner's former consort, and Briggs Hannon (William Gargan), aided by secret agent Secretary (Keye Luke). The villains, aside from Renner, all have disappointingly small roles, especially the excellent Turhan Bey, whose Captain Muto only shows up in the last reel. Many familiar Universal faces appear, such as Olaf Hytten, wearing Chinese makeup as the shopkeeper who helps Hannon crack the code, Edward Van Sloan, in for one sequence as one of Elena's allies, and Victor Wong, the Chinese cook in both "King Kong" and "The Son of Kong," seen aboard a train. Also familiar is Hans J. Salter's music score, almost entirely cribbed from "The Ghost of Frankenstein," released while this film was still in production. The lovely Irene Hervey easily stands out in the mostly foreign cast, and would next star in one of Universal's greatest wartime horrors, "Night Monster," opposite Bela Lugosi and Lionel Atwill, another SHOCK! title.
