It is the story of Laurel Mack, a divorced mom of two girls and one boy. One day, Ellie, the youngest, asks her mom to have a math tutor, but Laurel said no, cause it was too expensive.
But one day, her mom arrives at home with a woman. Her name is Noelle Donnelly. She is her new tutor. But Ellie found her really creepy with all of her weird questions and after a few meeting, she asks her mom to stop tutelage.
After Ellie stopped her tutelage, she met Noelle in the street. They talk and Noelle asks Ellie if she wants to pass at her home to take a practice paper that she uses with her other students. Ellie didn't want to but she accepts. Noelle shows Ellie a side road to show her that her house was near. No one never saw Ellie came in the little house. Nobody heard the door closes behind her. An then, she was gone.
Ha! Ha! Ha!
Ten years later, the police found the bones of Ellie Mack in the woodland. Ellie was dead. One months before her funeral, Laurel met Floyd...
