But there are no bears here. Not on Muffin's watch.One night, Muffin hears a suspicious noise. Mouse? Raccoon? Bat? Nope, not the usual suspects. But Muffin hears . . . growling. Could it be? Yup. A bear. Just a cub. Whose stomach is definitely growling. Muffin's got this case solved--clearly this bear needs some donuts.

    But now the treats are missing. What does Kayla know? There are three treats missing. King was in the kitchen. King's breath doesn't smell like peanut butter. What does King know? There's an intruder in the house. How will they solve the mystery?
