'Should a woman bear a child knowing that there are traces of insanity in her family? Linda Hainlin, niece of a famous biologist, was aware of the danger when she married Dr. Nigel Hendon, a practical idealist, whose creed was normality and the rational ordering of the world. This book tells how, years later, while temporarily deprived of her husband's sane companionship, Linda feels the oncoming of those homicidal impulses which presage madness. On this tragic theme, 'Prelude to Christopher' is written with strong literary art as a narrative of four days of crisis. The story goes back in memory to the happiness of Linda's love for Nigel, and forward in her frightened imagination to a future from which the strongest must flinch. Christopher, the unborn child, dominates terrific events in which he has no living part to play. The prelude to his birth is told with emotional power.'
