Monthly Film Bulletin said "An indifferent thriller, whose stock characters and situations fail either to convince or to excite. A humdrum production is scarcely relieved by Raymond Lovell’s performance as a blundering Inspector."

Kine Weekly wrote "Crowded and ingenuous "cops-and robbers” staged in and around London. ... The plcture occasionally allows its lively sense of humour to remove the edge off some of its thrills, but otherwise it's hearty, actionful and disarmingly ingenuous 'Boys’ Own Paper'."

TV Guide gave the film two out of five stars, calling it a "Silly spy drama ...The complicated plot doesn't quite work, but audiences should enjoy it anyway."

Allmovie wrote, "a little-known British melodrama with some potent talent involved, including actors Terence Morgan and Joan Rice and future Saint director Robert Baker".

In British Sound Films: The Studio Years 1928–1959 David Quinlan rated the film as "average", writing: "Light thriller is quite unconvincing, but so hectic it almost gets away with it."
