Charles Condomine, lead character of Noel Coward's comedy Blithe Spirit, should take heed of our superstit--uh, common wisdom. Condomine, a successful novelist, invites Madame Arcati, a medium, to dinner with intent of researching (or possibly exposing the charlatanry of) psychic practitioners for his next book. Despite his skepticism, Madame Arcati is able to summon the spirit of Condomine's first wife, Elvira, but quite unable to return the mischievous ghost to the spirit realm. It doesn't help matters that Condomine's second wife, Ruth, can't see the ghost, or that Elvira is bent on having Charles join her in death. Of course, English hilarity ensues. Or at least Richardson Theatre Centre's version of English hilarity will ensue, featuring Doug Fowler, Rachael Lindley, Meredith Morton and Rachael Schnitzius. Coward's play and RTC's production promise startling plot twists and farcical incidents that may end with more than one "blithe spirit."
