When Dunc and Amos are invited to spend a week in Scotland, Dunc can already hear the bagpipes a-blowin'. But when the boys spend their first night in an ancient castle, it isn't bagpipes they hear. It's moans! Dunc hears groaning coming from inside his bedroom walls. Amos notices the eyes of a painting following him across the room! Could the castle really be haunted? Local legend has it that the castle's former lord wanders the ramparts at night in search of his head!

Team up with Dunc and Amos as they go ghostbusting in the Scottish Highlands!
