Gideon Mack doesn't believe in God, the Devil or an afterlife. After he discovers a mysterious standing stone, his life unravels 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.
Robertson weaves into Mack's 'testament' acute insights into Scottish culture of the twentieth century, dramatizing the country's struggle to remain true to its history. An exceptional novel, which combines consummate storytelling with immense imaginative power.
