Critical reception
The Monthly Film Bulletin wrote: "An antediluvian stage play given appropriately primitive dialogue and direction, saved to a degree that it does not deserve by the faultless performances of Mary Merrall, Ellen Pollock and Amy Dalby as three three slightly weird old ladies. A word of praise, too, for Vanda Godsell's vixenish, vulgar personification of all that is monstrous in money-grabbing landladies."

Kine Weekly wrote: "This is a typical who-dunnit story in which almost anybody could be the guilty party and the fact that only 'murderer' was the corpse provides a pleasant twist. As entertainment, however, it suffers from a lack of cinematic ideas, both in script and direction. It is, in fact, hardly more than a collection of competent actors and actresses acting a play. The words, interesting and informative though they are, seem to go on and on and too little of the plot is told in action or by the moving nature of motion pictures. However, the twist ending is pretty well concealed, and the whole is partly redeemed by the excellent cast."

The Radio Times called it a "strange, dated mystery,"

TV Guide wrote "This little film has a strange premise, to say the least."
