The Mystery of Irma Vep is a play in three acts by Charles Ludlam. (A Penny Dreadful), Irma Vep is a satire of several theatrical and film genres, including Victorian Melodrama and the Alfred Hitchcock film Rebecca. Charles Ludlam ( April 12, 1943 - May 28, 1987) was an American actor and playwright. ... Penny Dreadful can refer to: The 19th century British penny dreadful publications. ... Rebecca is a 1940 film directed by Alfred Hitchcock as his first American project. ...

The play, despite featuring eight characters, was intended to be performed by only two actors, and is most entertaining when played in that manner. The actors play roles in both genders. The technical requirements of the show are considerable, as it requires a whirlwind of sound cues, props, special effects, and lightning-quick costume changes.

The plot centers around Mandacrest Estate, the home of Lord Edgar and Lady Enid. Lady Enid is Lord Edgar's second wife, though he has yet to recover entirely from the passing of his first wife, Irma. The house staff, a maid named Jane Twisden and a swineherd named Nicodemus Underwood; have their own opinions of Lady Enid.

Eight characters are played on stage, including: Lady Enid, Lord Edgar Hillcrest, Jane Twisden, and Nicodemus Underwood. Minor characters Alcazar and the Mummy Pev Amri also feature.

The play includes references to (and appearances by) Vampires, Ghosts, Mummies and Werewolves. It contains the occasional jibe of an adult nature, but is largely acceptable for audiences of all ages.
