In this first book we meet Karl, a reluctant German Shepard pup, who discovers that he is "Quick as Lightening" and can smell anything. He is selected for a police dog training program, where he becomes the star.

His training leads to Bob, his new human partner, Bob's cat BB the "Diplocat" and his new friend Frank, the tiny little dog with a big heart.

See how Karl deals with cats, smelly places and important police work in this sarcastic book about growing up.
