The Playroom — Frances Fyfield

Katherine and David have the perfect life: they are beautiful, rich, debonair, and gifted. But cracks begin to form beneath the smooth exterior when David suspects that one of their two children is not his. There is no other reason why chubby, petulant Jeanetta does not conform to David's standards of perfection and order.

Soon, David's mood swings become more violent and irrational. In an attempt to exercise some control over his world, he sends Jeanetta to the playroom . . . and locks the door. With harrowing precision, Fyfield tells the story of a family's descent into madness.
