Qwill's on his way to Scotland -- and on his way to solving another purr-plexing mystery. But this time Koko's nowhere near the scene of the crime.

Koko and Yum Yum are back in Pickax being coddled by a catsitter... but Koko won't sit still once Qwill's traveling party returns -- minus one member. He's behaving oddly, and Qwill knows what that means: Koko may have been miles away from the murder scene, but he's just a whisker away from cracking the case!
