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. He 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!
