Roger's version - John Updike

Middle-aged, brilliant and bored, Roger Lambert is a professor of Divinity at a New England university. Firmly convinced that religious belief can only justified by recourse to pure faith, he is dismissive when visited by a gangling student who claims, with evangelical zeal, that computer technology is on the brink of proving the existence of God. But when his unhappy wife flings herself into an affair with the younger man, and Roger's faith in his own placid life is thrown into question. With his marriage close to collapse, he finds himself increasingly drawn to his own half-niece, the nineteen-year-old Verna, in this cunning and comic exploration of religion, uncertainty and passion.
