Ever since its first appearance in 1886, Robert Louis Stevenson's Strange Case of Dr Jekyll and Mr Hyde has proven itself to be a tale of undiminished power for readers all over the world. But the story of the respectable Dr Jekyll, even in a London setting, has links that stretch back to the narrow wynds of Edinburgh and the bleak moors and shores of the North.This collection reveals the Scottish origins of Stevenson's great masterpiece of psychological fiction and his stories of possession, doubleness and terror, and uncovers his fascination with the uncanny which brought the creator of Mr Hyde screamingly awake one winter's night over one hundred years ago.
