Set in contemporary Scotland, the novel uses the literary device of a discovered manuscript the testament of Gideon Mack which has fallen into the hands of a journalist. A son of the manse, Mack has grown up in an austere and chilly house, dominated by a joyless father. Unable to believe in God, he is far more attracted by the forbidden cartoons on television. Father and son clash fatally one day and it may be guilt which drives Mack to take up a career in the Church. This minister, who doesn't believe in God, the Devil or an afterlife, one day discovers a standing stone in the middle of a wood where previously there had been none. Unsure what to make of this apparition, Mack's life begins to unravel dramatically until the moment when he is swept into a mountain stream, which pours down a chasm before disappearing underground. Miraculously Mack emerges three days later, battered but alive. He seems to have lost his mind however, since he claims that while underground he met the Devil. To this story, Robertson adds a wealth of insight about the mood of post-war Scotland on the brink of the social revolution of the Sixties, and dramatizes the country's struggle to stay true to its history while swimming within the powerful current of Americanization. Written with great lyricism, tight pacing, superlative storytelling and immense imaginative power, this is Robertson's most ambitious and accessible novel to date.
