Murder By Rope [1936] [DVD]

A maniac who sends warning letters to his victims and then strangles them with a rope is found guilty and hanged. Some time later, some one else does the same thing. The trial's judge, Philip Hewland, is threatened. Of course, this means he must hold a dinner party, during which there are sinister goings-on.

Director George Pearson had a long history in British movies, going back to 1913 as a writer and director for Pathe. Since the coming of sound, he had been relegated to cheap quota quickies. This, alas, is one of them, using all the standard tropes of British mysteries.
