Book excerpt: This is a collection of contemporary Scottish gothic fiction. As well as a bloody and turbulent history, Scotland has produced some of the world's most eerie and disturbing fiction. The national psyche seethes with Tam O'Shanters and Mr Hydes, justified sinners and wasp factories, monstrous apparitions, witches, doppelgangers and psychopaths. Here, a selection of Scottish writers have plumbed their depths, creating a set of demons for a modern age: Ali Smith's neo-Nazi, Alison Armstrong's transvestite serial-killer, Brian McCabe's abominable neck-boil, James Robertson's mutant mouse, Toni Davidson's confused sado-masochist. Be frozen by Maggie O'Farrell's quiet touch or be appalled at Andrew Murray Scott's putrescent landscape. Experience fork and knife disorder with Jackie Kay or receive sinister letters from Helen Lamb.
