Silent children

Hector Wollie "rescued" children from abusive parents by murdering them and then disappeared. Horrified to learn that her house was the site of one of Wollie's murders, Leslie can't afford to move, and worries how this will affect her 13-year-old son, Ian. But Wollie "never" left. When Ian and his younger stepsister soon disappear, no one knows that they are right next door.
