Murder She Said (1961) - PAL RoSub - by Laur

On a train home after a shopping expedition, Miss Jane Marple (Dame Margaret Rutherford) sees a woman being strangled on another train that is travelling alongside her own. She reports it to the conductor and the Police investigate, but can find no evidence of foul play and no body. Along with her friend Mr. Stringer (Stringer Davis), she determines that if the body was thrown off the train, it would have to be in the vicinity of Ackenthorpe Hall. She wrangles a post as cook at the hall and soon becomes quite friendly with the youngest of the family, Alexander (Ronnie Raymond). Working there gives her plenty of time to search the grounds, and despite the crusty old Ackenthorpe's (James Robertson Justice's) complaints - he's under the care of the local Dr. Quimper (Arthur Kennedy) for any variety of ailments - she finds the woman's body hidden in one of the outbuildings. Having established that someone was killed, it's left to Miss Marple to determine who she is and who wanted her dead.
