Hitchcock is a director with an exceptionally acute ear. He achieves his results by a Ravel-like rhythmic pummelling of the nervous system. Music, sound effects, the various equivalents of squeaking shoes, deep breathing, disembodied voices are mingled in the telling of the tale with a mounting accumulation of small descriptive touches that pyramid the tension.

9/10The first time Hitchcock has revealed his psychological attraction to the association between sex and murder, between ecstasy and death. Montagu's claim that Hitchcock's edit contained up to 500 intertitles seems likely an exaggeration, but he worked with the director during the summer months to tighten up the film. One of the other improvements was to hire American poster artist Edward McKnight Kauffer to design the animated triangular title cards.
The trade journal suggested the film could be the finest British production ever made, indicating extremely high praise.
