Werewolf? There, wolf: Right there in the Riffe Center, where CATCO is ending its season with a hilarious and horrifyingly good production of The Mystery of Irma Vep. First staged by Contemporary American Theatre Company (CATCO's original name) with great success in 1990, Charles Ludlam's satiric Gothic horror-thriller is worth reviving with the right cast, attitude and top-notch design team.
