The Monthly Film Bulletin wrote: "A commonplace mystery story, with a confused plot, a certain elementary suspense and some artificially contrived excitements."[3]
Kine Weekly wrote: "The picture occasionally gets caught up in its own cross-currents, but choppy moments are few and it puts plenty of punch into its concluding episodes and climax. Richard Arlen is virile and likeable as Martin, Donalds Houston registers as the resolute Mallard and Greta Gynt makes a comely Peggy. The supporting players also keep on their toes."[4]
Variety wrote: "The melodramatics in this British-made thriller that 20th-Fox is distributing come off poorly and it is best suited for fill-in bookings in the lesser situations. Only familiar name is that of Richard Arlen, balance of cast being Britishers. ... The basic plot idea furnished a good enough springboard for a program meller, but it falls apart in the script development, giving the players little to work with. Montgomery Tully's direction is no help, either, so there's no plausibility to the action. The technical contributions are substandard."[5]
In British Sound Films: The Studio Years 1928–1959David Quinlan rated the film as "mediocre", writing: "Very artificial thriler of little interest."[6]
