S08E01 - The Murder of Roger Ackroyd

The story begins with the death of Mrs. Ferrars, a wealthy widow who is rumoured to have murdered her husband. Her death is initially believed to be suicide until Roger Ackroyd, a widower who had been expected to marry Mrs. Ferrars, is found murdered. The suspects include Mrs. Cecil Ackroyd, Roger's neurotic hypochondriac sister-in-law who has accumulated personal debts through extravagant spending; her daughter Flora; Major Blunt, a big-game hunter; Geoffrey Raymond, Ackroyd's personal secretary; Ralph Paton, Ackroyd's stepson and another person with heavy debts; Parker, a snooping butler; and Ursula Bourne, a parlourmaid with an uncertain history who resigned her post the afternoon of the murder.
