It's no mystery: Chet Gecko can't sing. He can't dance. He can't act. Heck, he can't even act normal . So why would he take the lead in Mr. Ratnose's musical version of Shakespeare's Omlet, Prince of Denver ? A new case, naturally. The original leading man has disappeared, and something smells rotten in the realm of Ratnose. Did the third-act lip-lock with Shirley Chameleon scare him away? Or is foul play afoot? One thing's for certain: This mystery won't be over until the fat gecko-er, lady-sings.
