Strange things are happening at Drumtipperty Castle... Ghostly things... Heir to one of the oldest castles in Scotland, Hamish lives with his father, Laird Montgomery, and pony-sized dog Gorse. His mother mysteriously disappeared five years ago. The castle is falling apart. And with no cash to fix it, the Laird concocts a series of money-making plans. When each and every one fails (mostly because of Hamish), it's up to the ten-year-old to save their ancient family seat. Finding the long-lost Montgomery Claymore would solve EVERYTHING. But not only is the Scottish sword missing, it's cursed, too. And while the castle's dungeon could hold the secret to uncovering it, a dark secret looms inside.
