The Testament of Gideon Mack is James Robertson''s acclaimed novel exploring faith and belief.

For Gideon Mack, faithless minister, unfaithful husband and troubled soul, the existence of God, let alone the Devil, is no more credible than that of ghosts or fairies. Until the day he falls into a gorge and is rescued by someone who might just be Satan himself.

Mack''s testament - a compelling blend of memoir, legend, history, and, quite probably, madness - recounts one man''s emotional crisis, disappearance, resurrection and death. It also transports you into an utterly mesmerising exploration of the very nature of belief.
