Orkney storyteller Tom Muir weaves tales from Scotland's lore-steeped shoreline, finding selkie folk, pirates and even the devil in the liminal space between land and sea. Learn how death was captured in a nut, how a mermaid wreaked her revenge and how whirlpools were created. Discover a land beneath the waves, the mysterious island of Tir-nan-Og and a chorus of demon cats - but beware the most grotesque monster of them all, the hideous Nuckelavee
