In the back of the programs for Spokane Civic Theatre’s new production of “Clue: The Musical,” there’s a page of grids and boxes that asks, “Can you solve the mystery before our detective?” Just like in the classic Parker Brothers board game, a murder has been committed, and it’s up to us to determine the who, the where and the how: There are six suspects, six possible weapons and six potential locations, and we’re supposed to take notes that will help us deduce the identity of the culprit. That’s the niftiest invention of the show, directed by Keith Dixon, which, while not a particularly memorable piece of theater, has a lot of goofy energy. It’s set, as these types of stories always are, in a creaky, old mansion where a dinner party is being thrown. Mr. Boddy (Ben Dyck) is our host, and he announces from the get-go that he’ll soon be murdered by one of his guests. The show isn’t so much about who eventually kills him, but rather who will get to him first.
