Middle-aged brilliant & bored Roger Lambert is a professor of Divinity at a New England university. Firmly convinced that religious belief can only be 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 & Rogers 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 & comic exploration of religion uncertainty & passion.
