Valerie had always believed the worst thing a mother could face was losing a child. Five years earlier, after a difficult delivery, Spencer told her their newborn son, Oliver, had died before she could see him. Eleanor repeated the story until Valerie stopped asking questions. Yet strange dreams of a crying baby never left her. When Valerie recently hired Rosa as a nanny, she became convinced Rosa was neglecting the children, so she secretly installed cameras throughout the house. At 3 a.m., one camera suddenly showed Spencer entering the nursery in black gloves. Eleanor followed him carrying a medical bag. Then Valerie saw Rosa hiding inside a closet, clutching baby Matthew and covering his mouth. Valerie stared at the screen, terrified and confused. Suddenly, another camera picked up a tiny voice from somewhere beneath the house. “Mom.” Valerie froze instantly. She knew that voice could not belong to Matthew.
