Halloween 1921. A castle on a rock in a lonely Scottish loch, Braeburn has been crumbling for centuries. Someone tries to remedy the rot but uncovers a skeleton behind a wall. It wears a crown upon its skull and hides a curse within its bones. Is it the ancient King of the Isles? Or is it Black Dougal? And why is it surrounded by mystery?

As ghosts are heard and treasure seekers arrive, the Braeburn's call Major Heathcliff Lennox. He travels to the Highlands to help his old friends, taking his dog, his butler and his small cat. 
Major Heathcliff Lennox, ex-WW1 war pilot, 6 feet 3 inches, tousled, dark blond hair, age around 30 - named after the hero of Wuthering Heights by his romantically minded mother - much to his great annoyance.
