If the devil didn't exist, would man have to invent him?

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 is a compelling blend of memoir, legend, history and, quite probably, madness and 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.
