This book is selected by Rosemary Gray. Scotland has a notoriously rich and diverse cultural tradition when it comes to the supernatural. Many of her greatest writers from Sir Walter Scott and James Hogg to Robert Louis Stevenson and John Buchan have explored the country's unique folkloric heritage to spine-chilling effect. From Highlands to Lowlands, from blasted heath or remote glen to wretched hovel or austere castle, the very topography lends itself somehow to the strange and unexplainable. Leading off Edinburgh's colourful Royal Mile, which runs from the Palace of Holyrood to the gaunt castle on the rock, there are many narrow 'wynds' - passages ancient and mysterious.
