The film was reviewed by C. A. Lejeune in The Observer of January 10, 1937 when he said that it, "was a bit slow in getting started, but once the extra characters of the early scenes are dropped and the film gets the two leading players alone in their Kentish farmhouse, it becomes a hair-raiser of the first order." He concluded that, "Ann Harding and Basil Rathbone…overplay a little in the final conflict, but I'm not at all sure that it isn't what is wanted for the picture. The whole treatment of the climax is strained, overwrought, and hysterical; on the border-line between laughter and madness. There is one shot, when the wife throws open the last door to escape and finds her husband standing dead-still on the threshold, that hasn't been equalled for horror since Cagney's body fell through the doorway in Public Enemy. A woman in front of me let out a scream like a steamship siren at this point in the first performance. That scream was the natural voice of criticism testifying to the film's success."
The Scotsman of June 22, 1937 started off its review by saying, "Suspense is cleverly created and sustained in this film version of the late Frank Vosper's play." The reviewer continued, "The suspicion that she has married a murderer is cunningly built up; his homicidal mania, strangely mixed up with greed and sadism, is made plausible and eerily convincing; and the closing sequence, in which the wife, sensing his murderous intention, seeks frantically, almost despairingly, for some escape, achieves dramatic suspense of an intensity only occasionally encountered on the screen. Much of the effect is due to the acting. Ann Harding brings a strong, yet restrained emotion to her part, even when it trembles of the verge of melodramatic insanity, and Basil Rathbone terrifyingly combines sensitiveness and insanity in a polished and persuasive performance."
