The Barries and Davies socialize, but Mary and Arthur each quietly resent Barrie Mary for neglecting her, and Arthur for imposing upon his family. Sylvia and Arthur have two more sons, Michael and Nico, whom Barrie adds to his circle of young friends. He writes a play inspired by them Peter Pan, or The Boy Who Wouldnt Grow Up, which is a great success for him and his producer friend Charles Frohman William Hootkins.Arthur is struck by a disfiguring and ultimately fatal cancer.

With George away at school, sensitive Michael becomes the centre of Uncle Jims attention. Tired of her husbands indifference toward her, Mary falls in love and has an affair with Barries young colleague Gilbert Cannan Brian Stirner. When Barrie finds out, Mary refuses to end the affair, and he reluctantly grants her a divorce. Meanwhile, Sylvia has fallen ill with cancer, and dies a few years after her husband.
