Death at the Lamplight Theatre

From BoardGameGeek:

The air has a chilly nip to it. Snow is falling lightly. The holidays are almost here. The Lamplight Theatre is in the middle of a run of performances of Dickens' "A Christmas Carol." Reviews have been good, and ticket sales have been even better. Yet, things in Valley Falls never stay happy and festive for very long. When Victor Day, the lead actor playing Ebenezer Scrooge in the performance, is found dead, the show's future is called into question. Evidence points to one of the members of the cast and crew being responsible. Can you solve the case of "Death at The Lamplight Theatre?"
