Blithe Spirit by Nöel Coward
Charles Condomine, whose first wife Elvira has been dead for seven years, has been reasonably happy with his second wife Ruth. After he invites Madame Arcati, a local medium, to conduct a seance at their home, Elvira returns from the dead. Determined to get Charles to herself forever, she arranges several "accidents", one of which culminates in Ruth joining Elvira.
Now plagued by two jealous squabbling spirits, Charles bids them both farewell and his two wives are left petulantly tearing the house apart.
