A set-in-his-ways housecat has his routine upended by an enthusiastic new puppy with a nose for solving mysteries in this first "effervescent" (Publishers Weekly) book in a graphic chapter book series perfect for fans of InvestiGators and Narwhal and Jelly.

Truffles the cat is the only pet in the house and reigns in peace and quiet, only exerting himself to find the best place to take a nice, long nap--preferably in a spot of warm sunshine. Then Poppy the puppy bursts onto the scene.

Poppy is loud, enthusiastic, excitable, and--worst of all--a puptective! She's got an eye for crime and a nose to solve all mysteries that come her way...even though she's not completely sure what a mystery is.

Truffles cannot let this intrusion stand. Poppy won't be able to continue disrupting his precious me-time if she's shipped to the North Pole! But could this irrepressible new companion be just what this grumpy cat needs?
