At Wendell Wilke High, Christmas may not come at all if Principal Crunge has his way.  The reason?  Santa Claus is missing!  During the last rehearsal for the annual Christmas Show, the action comes to a screeching halt when the cast discovers that the Santa Claus statue, the highlight of the final number, has been stolen!  ’That’s it!’ intones the principal.  ’No Santa, no show!’ Finally, Mrs. Dickens, the director, urges him to give them a chance to find the missing St. Nick.  She immediately calls in the Clue Club — a group of five ambitious and eccentric students who take mystery and detection into the realm of science.  Lines, accusations and motives fly fast and furious as each student, from the jock who’s in the show on a bet, to the girl who has a crush on the stage manager, becomes a suspect, along with the costumer, stage manager, school receptionist, janitor and even Mrs. Dickens.  Full of more surprises than a fruitcake, the Clue Club finds they have successfully fulfilled their duty as ’Christmas Scene Investigators’ when they reveal just why the true meaning of Christmas is all that really matters.
