The Boggart and the Monster
Susan Cooper Audio Book

On a visit to their former home, Castle Keep, Emily and Jessup Volnik are delighted to find that the Boggart is still there.

The Boggart is a mysterious shape-shifting spirit who has lived in the castle for centuries, playing tricks on the owners. Now he is making the current owner, Mr Mac, doubt his sanity as strange things happen...

Jessup persuades Mr Mac to take them on a camping trip to Loch Ness, and the Boggart comes along. On the first night, he rediscovers a long-lost relative—Nessie, the Loch Ness Monster!
