"Arthur doesn't always remember where he buried his bone, or what he was doing before he started scratching his ear, but he never forgets three importants facts: Bacon is delicious. He loves his humans, twins Bro and Harmony, with all his heart, and Queenie the Cat is out to destroy him. When Queenie the Cat wins first place in a feline beauty contest at the county fair, Arthur expects her to be snootier than ever. Yet when Queenie returns from the fair, she seems oddly nice and sociable, almost like she's had a personality change. The humans chalk up Queenie's good mood to her recent win, but Arthur knows the truth. He can tell from the smell that this friendly Queenie is an imposter. But before he can decide what to do, Cuthbert the clown, the only person who knows what's really going on, goes missing. Can Arthur solve a mystery on his own? Or will he have to accept that he needs Queenie as much as he needs bacon?"--Adapted from dust jacket.
