Rent The Unpleasantness at the Bellona Club (1973)

Ian Carmichael stars as the aristocratic detective Lord Peter Wimsey in this classic BBC adaptation of the novel by Dorothy L. Sayers. Lord Peter is called upon to investigate the death of the aged General Fentiman who apparently died peacefully in his chair by the open fire at the Bellona Club. It would have been dismissed as simply old age, had the exact timing of the General's death not been vital to the distribution of a huge inheritance. Lord Peter's investigations lead him into deeper water than anyone expects and, when it becomes clear that the General was murdered, the list of suspects is long.
