Ella is on her way to a conference for florists in London. She is taking the train and is bored. She notices two teen girls, Anna and Sarah, and eavesdrops on them. They are soon joined by two older boys, who have just been released from prison. Ella keeps her eye on them and wonders if she should try to contact their parents, since she overheard their names and where they are from. Ella decides she is being a prude and does nothing. The next day on the news, Anna is reported as missing.
A year later, Anna is still missing and there are no leads. Ella had come forward at the time and the two guys were never found. Ella lives with the guilt that she could have done something. Now she is receiving anonymous notes in the mail telling her she is being watched. Ella thinks it is Anna’s mother sending the notes. She hires a private investigator to find out what is happening. Also, around this time a new documentary about the disappearance is aired. This brings some new clues to light. Will Anna’s disappearance finally be solved?
This was a good psychological thriller. It kept me guessing until it was revealed what really happened to Anna. I eagerly am waiting for the next book by Teresa Driscoll that comes out in March, The Friend.
