Critical reception

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"; while 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"; and Fantastic Movie Musings and Ramblings concluded, "It's a British B-movie thriller with slight touches of noir to it, and it's moderately entertaining. It's worth a look for the curious, if you can find it."
