As the madman, with a childish, increasing uneasiness, awed by the sinuous approach of the unseen fire, might pace to and fro, round and round about his cell, so it seemed to this poised, watching faculty of Valentine that his soul wandered in its confined cell of the body, at first with the cushioned softness of an animal, moving mechanically, driven by an endless and unmeaning restlessness, then with an increasing energy, a fervour, a crescendo of endeavour.

What drove his soul?
