"We think we know the ones we love.” So Pearlie Cook begins her indirect and devastating exploration of the mystery at the heart of every relationship: how we can ever truly know another person. It is 1953 and Pearlie, a dutiful young housewife, finds herself living in the Sunset District in San Francisco, caring not only for her husband’s fragile health but also for her son, who is afflicted with polio. Then, one Saturday morning, a stranger appears on her doorstep, and everything changes. All the certainties by which Pearlie has lived and tried to protect her family are thrown into doubt. Does she know her husband at all? And what does the stranger want in return for his offer of a hundred thousand dollars? For six months in 1953 young Pearlie Cook struggles to understand the world around her, and most especially her husband, Holland.
