Blithe Spirit is a comic play by Noël Coward. The play concerns the socialite and novelist Charles Condomine, who invites the eccentric medium and clairvoyant, Madame Arcati, to his house to conduct a séance, hoping to gather material for his next book. The scheme backfires when he is haunted by the ghost of his annoying and temperamental first wife, Elvira, after the séance. Elvira makes continual attempts to disrupt Charles's marriage to his second wife, Ruth, who cannot see or hear the ghost.
The play was first seen in the West End in 1941, creating a new long-run record for non-musical British plays of 1,997 performances. It also did well on Broadway later that year, running for 657 performances.
