Nemesis (1) - S2.E5

Miss Marple is sent by a dead millionaire on a coach tour to secure justice, although for whom is unclear. Vowing to find out the truth, and accompanied by her nephew, she links the millionaire to a dead girl, Verity Hunt, and a family of sisters who live in a ruined manor house. Another death takes place before Miss Marple discovers that love, as well as hate, can be a reason for murder.
