The Monthly Film Bulletin wrote: "Unpretentious East-West espionage story in a continental setting. The locale and atmosphere are fairly convincing and the plot is adequately sustained, but credibility is ignored towards the end, when a prowler is loose in the well-guarded grounds and, although armed with a rifle with telescopic sights, fails to kill at twenty yards range."^[3]

Kine Weekly wrote: "The picture, which, incidentally, far from flatters Military Intelligence, is little but talk for the first hour. Wayne Morris, sound as the roughly handled Tom, Norman Wooland, all agog as Cleaver, and Tilda Thamar, Mary Mackenzie and Marjorie Stewart, suitably contrasted as the women, try to keep the conversation clear and crisp, but it is only during the last 20 minutes that sparks fly. The denouement is, however, first rate theatre and gets the headline hokum over."^[4]

TV Guide wrote, "the intriguing story suffers from inefficient production techniques."^[5]
