The Monthly Film Bulletin wrote: "This story is full of complications which scarcely compensate for the lengths to which the basically simple plot is stretched. A weak script gives the cast very little opportunity for performances, and in the circumstances they make their parts as credible as could be expected."[5]
Variety wrote: "It is a routine spy story of poor quality that will be adequate in U.S. only for lower case double-bill bookings. ...The cast performs adequately under Wiider's direction, but not to any advantage, their own or the picture's. The continuity is confusing and finally annoying. The photography, by Jim Harvey, is often interesting, but it has a curious composition. It consists almost entirely of medium close-ups, two or three-shots, and closeups, indicating it was shot with television, not feature picture release in mind. Very little advantage is taken of the foreign location."[6]
