O'Connor wrote: "Miss Christie would no doubt approve of Joan Hickson, the veteran British character actress who plays Miss Marple... This BBC/Arts & Entertainment co-production offers an especially good example of Agatha Christie in adaptation.  The characters are nicely realized and the suspense holds.  Miss Hickson is lovely, neither as awesome as Miss Rutherford nor as overly cute as Helen Hayes.  And the supporting cast is admirable, particularly Gwen Watford as Dolly and David Horovitch as Inspector Slack.  As someone notes about the case, 'you'll have to admit it has all the bizarre elements of a cheap thriller.'  Once hooked, you won't be able to turn it off."
