This really is a very readable book - the pages just seem to turn themselves, and I raced through it in two or three days. It tells the story of a Scottish Presbyterian minister, living in a remote village, where as one would expect, he is a prominent citizen. He has ministered at the church for many years, and his congregation know him well, and mostly respect his contribution. All this is to change however, for Gideon Mack goes walking one day, soon after his wife has died, and falls into a great chasm, with a raging stream at the bottom of it, and is swept into an underground cave, where he is rescued from the waters, by Satan.
Satan of course, does not have horns and a red cloak, but dresses in a scruffy casual way, and almost immediately steals Gideon's boots, exchanging them for a pair of old trainers (the only visible evidence Gideon brings back to the world above when eventually he returns home). I will not recount what happens next, but needless to say, an encounter with Satan is as life-changing as an encounter with God himself, but not necessarily in a way the reader would expect.
Gideon is a complex person, a Minister with little belief left, and a friend of atheists and sceptics, rather than the staunch church-goers of his congregation. We read about his childhood (in a strict Scottish home, his father himself a stern minister) and education, his courtship and marriage and his calling to the ministry. We find someone keen to do good in the world, despite his lack of an evangelical conviction. All goes reasonably well until his wife dies, and then his world slowly starts to unravel, leading him to adventures and experiences denied to most Presbyterians. Poor Gideon, we grow to like him, and we follow his progress with interest and understanding. He is all to human, but his calling has dictated a style of life and manners which rarely seems the natural way for a whole lifetime.
The final unravelling is dramatic and moving, and as Gideon disappears from our lives, like all good fictional creations, we miss him and wonder what happened next. A fine, clever, entertaining novel, well worth a few hours of anybody's time.
