The Monthly Film Bulletin wrote: "A potentially horrific theme is treated with little sensationalism. In fact both script and direction often have an air of the respectable village dramatic society about them. Howard Pays' sinister lines are heavily stressed for all to recognise them and most of the action takes place in one living-room where people are always popping in and out. The dialogue tends to repeat the obvious, the motivation for the second crime is ambiguous, and the errors that betray the killer are unbelievably blatant and inconsistent with his earlier cunning. Terence Knapp gives a sympathetic and convincing performance in the better constructed part of Hughie, the simpleton."
Kine Weekly wrote: "The script eschews subtlety, but cast and director play upturned aces and court cards skilfully and temper suspense with human interest. ...Howard Pays registers as the schizophrenic Ramskill; Terence Knapp excrcises restraint as the jibbering, though harmless, Hughie; Ruth Dunning has her moments as Auntie B; and Patrick Barr is most professional as Allen. There is little comedy relief, but the domestic asides are quite touching, and the finale Is tense." == References ==
