Trish is gone.

The day after Trish's night with Bobby, Trish's best friend, Giulia, and her two sidekicks go to Mary's office. Mary knew something was up.  Giulia says that Trish didn't report to work and that is unusual. Mary and the girls then go to Trish and Bobby's home to investigate. There is no sign of Trish being forced out of the house. In fact, the author describes in great detail the house, with its white walls and contemporary minimalist furnishings. As Mary walked through the house, I almost felt I was there because of the author's imagery.

Since the girls don't find anything suspicious, they go to the police department to report Trish missing. Mary knows something isn't right because she found Trish's diary in Trish's car. In the diary, there are pictures of the injuries that Trish receives from the abuse. Mary decides that she can't say no to this case because she is confident she can find Trish alive.
