On that same day, August 3, 2013, Anna is home alone with the baby while Tom is out with his army friends. She can't stop thinking about Rachel's having been in the neighborhood that Saturday night. Although the police think that Rachel is nothing but a rubbernecker, she feels that they do not know how dangerous she can be.
Anna allows a peek behind the facade of the happy family she painted in an earlier chapter. While Tom is out with his friends, she feels stuck at home with the baby. Similar to Megan and Rachel, she feels suffocated by her current life and longs for a past she lost. She misses her old life as a working woman engaged in an affair with a married man, a life not mired by the responsibilities of motherhood. She immediately feels guilty for that thought and admits that she wants to protect what she has. She can't stand thinking about what might have happened to Megan or about Rachel's presence in the neighborhood that evening because both their stories illustrate how easy it is to lose the illusive safety and security of her lifestyle.
