TV journalist Tab Holland assists Scotland yard with the murder of a reclusive millionaire whose corpse is discovered locked in a vault. The key to the vault is mysteriously found on the table beside the corpse.
The Monthly Film Bulletin wrote: "A listless attempt is made to bring this old-fashioned Edgar Wallace thriller up-to-date by introducing a television announcer, contemporary furniture and nylon thread. Played in period, the heavy-handed melodrama might have seemed more convincing. As it is, with its Chinese manservant, vaulted treasure and fortune made "out East" (to say nothing of the footling trick with key and pin on which the plot revolves), it is merely an unlikely oddity among second feature thrillers."[4]
TV Guide called it "slightly better than most of the 47 Edgar Wallace second features that producer Greenwood put out between 1960 and 1963."[5]
