Book excerpt: A chilling tale from the bestselling author of The Devil’s Advocate, “a master of psychological thrillers” (V. C. Andrews). They were four perfect little children. Alex had taught them well. They helped with the house, set the table for meals, and went straight upstairs after dinner to do their homework. They did as they were told. Sharon didn’t miss the glances that passed between her husband and the foster children. From the day they arrived, they had looked up to Alex, worshiped him. Why, it even seemed they were beginning to act like Alex—right down to the icy sarcasm, the terrifying smile, and the evil gleam in their eyes when they looked at her. Oh yes, they’d do anything to please Alex. Anything at all . . .
