When there's a trouble at the Museum of Feline Art, Rider and the PI Pack arrive to find a new detective already on the scene. Wolf Growler is a super sleuth with crime-solving chops and he is paw-sitive he has this case solved. Can Rider prove that this rival detective is all bark and no bite, or will one of the PI Pack members get collared from a crime they didn't commit?
