Chet has smelled a lot of unusual things in his years as trusted companion and partner to P.I. Bernie Little, but nothing has prepared him for the exotic scents he encounters when an old-fashioned traveling circus comes to town. Unfortunately Peanut, the headlining pachyderm, has gone missing. How does an elephant vanish without a trace? Hired by Popo the Clown--who has his own reasons for wanting to find out what happened--Chet and Bernie are in hot pursuit after Chet takes a few sniffs in Peanut's trailer and picks up her one-of-a-kind scent.
