The story is fascinating, but also highly abrasive, it is not always pleasant to listen to. This is not the fault of the speakers, they did a great job.
The misery of lost love, the end of a marriage, the shards of a broken life and the rapid decline into alcoholism are too real and the emotions too raw to be taken as entertainment. Unfortunately this side of the story rings very true, while some of the aspects and details of the later crime cross the line of the plausible.
Rachel, the heroine of the story, lost her job, because of her drinking problems, but continues to commute every day to London to keep up appearances. Every day she passes her former home, where her ex-husband now lives with his new wife Anne and their little baby daughter Evie. Every morning she also watches a young couple, some houses down the road and fantasizes about their live. She calls them Jason and Jess. In her romantic dream world the life of this couple turns into everything she wanted to have, but lost forever. One day Jess goes missing and somehow Rachel is drawn into that mystery and she feels forced to find out, what happened.
The story is painfully slow at times, but there is enough tension built up to keep you going. It is after all a good book.
