The Monthly Film Bulletin wrote: "By more ambitious direction much more could have been made of this interesting story. After a promising beginning the film peters out into something very ordinary. Few of the supposedly tense situations are well sustained. Basil Radford impressed as the British Secret Service agent. The settings are appropriate."
Kinematograph Weekly called it "all very sweet and pretty but a modern audience is apt to demand more of espionage farce."
Picturegoer wrote: "The formula is fairly familiar. Action is sacrificed in the overstressing of the love interest, but the climax carries a fair thrill. Basil Radford plays Richardson in the well-known 'silly ass' secret service man tradition and Silvia St. Claire shows promise as Helen, but Thorley Walters overdoes the sensitive moments as Max and is frequently in danger of provoking laughs in the wrong places."
Picture Show wrote: "This picture, though not without sate fine melodramatic scenes, is very much the type of old-fashioned spy story which we enjoyed in the days of the silents. Nothing is left to the imagination, but some of the methods used appear to be very clumsy."
Variety called it "a consistently reasonable tale. with good, often brilliant dialog, splendid suspense, artistic production, good photography and intelligent direction. Acting is competent with the lone drawback being the lack of marquee names." ==References==
