The Voice of Merrill

The Voice of Merrill a.k.a. Murder Will Out is a 1952 British mystery film, directed by John Gilling and starring Valerie Hobson and James Robertson Justice. The Voice of Merrill was made by Tempean Films, the company owned by the films producers Monty Berman and Robert S. Baker, which between the late 1940s and the late 1950s specialised in turning out lowbudget Bmovies as unpublicised secondfeatures for the UK cinema market. On its release however, The Voice of Merrill was recognised by its distributors, Eros Films, as unusually sophisticated and stylish for a Bmovie, and was elevated to the status of cofeature in cinemas.

Allen has fallen in love with Roches wife Alycia Valerie Hobson, who is tired of her loveless marriage and frustrated by her overbearing, obnoxious husband, and the pair begin an affair. It transpires that Roche is suffering from a heart condition and is not expected to live much longer. He has written an episodic radio play The Voice of Merrill, and agrees to Alycias suggestion that Allen should be the narrator on the broadcasts. Alycia and Allen hatch a plot to pass the work off as Allens in an attempt to boost his career. Going further Alycia then decides to poison Roche in such a manner as to pass undetected as murder, trusting that his death will be attributed to his medical condition and will not arouse suspicion. Roche dies, and Alycia is horrified to be informed that an autopsy will be necessary. Allen tells her that he will confess to the murder rather than see her charged, and she attempts to dissuade him. However the autopsy results come back clear Roche did not die from poison, and the couple believe that they are off the hook.Unbeknownst to Alycia and Allen however, prior to his death Roche had discovered what was going on. Knowing that Parker is in severe financial trouble and bribing him with a large amount of cash, he has set up an elaborate posthumous revenge on the couple. Meanwhile, as the episodes of The Voice of Merrill are broadcast, Thornton begins to suspect that the storyline is pointing him in the direction of the blackmailers killer. ........
