The Philosopher's Pupil - Iris Murdoch

In the English town of Ennistone, hot springs bubble up from deep beneath the earth. In these healing waters the townspeople seek health and regeneration, rightousness and ritual cleansing. To this town steeped in ancient lore and subterranean inspiration the Philosopher returns. He exerts an almost magical influence over a host of Ennistonians, and especially over George McCaffrey, the Philosopher''s old pupil, a demonic man desperate for redemption.
