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. But Peanut, the headlining elephant of this particular one-ring circus, has gone missing—along with her trainer, Uri DeLeath.

After Chet takes a few sniffs in Peanut’s trailer and picks up her one-of-a-kind scent, he and Bernie are in hot pursuit, heading far away from the bright lights of the traveling show and into the dark desert night.

Some very dangerous people would prefer that Chet and Bernie disappear for good and will go to any lengths to make that happen. Across the border in Mexico and separated from Bernie, Chet must use all his natural strength and doggy smarts to try to save himself—not to mention Bernie and a decidedly uncooperative Peanut, too.
