The Monthly Film Bulletin wrote: "The familiar crime-and-detection formulas are applied in a manner conventional to the point of dullness; and the acting does little to brighten things up. Perhaps the reason the scenes in the operating theatre (reminiscent, as they are, of something better) achieve so little tension is because the locale itself has become so stereotyped."^[4]

Kine Weekly wrote: "Unpretentious and untidy British thriller. ... The cast contains popular names, but the leading players fail to achieve the impossible and seal the many loopholes in its sketchy script. Both surprise and punch are lacking. ... The picture has a novel idea, but its ingenuity is dissipated by unsubtle treatment. John Stone does a neat job as Inspector Price, but Tom Conway and Patrick Holt are forced to behave as if they want their heads examined as Doctors Wayne and Bowen and Sandra Dorne is completely wasted as Wayne's extravagant wife. The staging, too, leaves something to be desired, and so does the dialogue. Definitely made on frayed cuff."^[5]

In British Sound Films: The Studio Years 1928–1959 David Quinlan rated the film as "poor", writing: "Dull drama, described by one critic as 'clinical claptrap'."^[6]
