Kinematograph Weekly said: "Unhurried but reasonably well acted, it holds the interest even if it fails to chill the spine".[4]
Monthly Film Bulletin wrote: "As a thriller this is poor, the successive interviewing of the suspects one by one inducing positive tedium. The film, however, has one bright aspect: the amusing caricature of girls' school life it provides."[5]
Picturegoer wrote: "Barbara Murray gives an intelligent and credible characterization as one of the suspects. And the cast as a whole is efficient, but too verbose."[6]
Picture Show wrote: "'The school backgrounds are authentic, and the petty niggling and feuds of the mistresses seem very real also. It is well told, with tension and humour intermingling. Well acted and neatly directed."[7]
The Daily Film Renter wrote: "Not many fireworks are found in the story, but it proceeds gently along and we learn a good deal about school life through the eyes of the teachers. The film is pleasantly acted but the dialogue too often betrays its literary parentage."[8]
In British Sound FilmsDavid Quinlan described the film as: "Verbose, monotonous whodunnit."[9]
