Kid Caramel is on the case again. But this time his mystery is international. His classmate's grandfather is missing and Kid and his best friend Earnie offer to lead the search to find him...thousands of miles away in Scotland!

Kid is out of his element in this land of castles and lords. There are the strange noises in his friend's castle, the suspicious behaviour of family friends, and of course tales of the infamous Loch Ness monster. Who, or what, is responsible for Grandpa's disappearance? Will Kid Caramel's Sleuthing skills be enough to solve this trans-Atlantic mystery?
