It's Professor Plum in the Parlor with the lead pipe, or is it? For the Rhode Island premiere of Clue the Musical, Mr. Boddy's murder takes center stage at the Courthouse Center for the Arts. The interactive musical starts with three audience members selecting one card each from three oversized decks and placing it in an envelope marked "Confidential." The envelope is then left untouched until the end of the production. The chosen cards will determine the ending of the show, which has 216 possible conclusions.
