Rachel’s daily commute takes her past the neighborhood where she once lived, when she was married. The train frequently sits for several minutes at a railstop right behind the back yard of a young couple whom often Rachel spies sitting on their patio; she has built up an elaborate fantasy existence for these two, fueled by the unfulfilled wishes of her own failed marriage. One day Rachel sees the woman kissing someone other than her husband, shocking her out of her fantasy. Shortly after that, she hears that this woman has disappeared under mysterious circumstances. Convinced the strange man being kissed has something to do with the disappearance, Rachel goes to the police, only to be dismissed because of her well-known drinking problem. Undeterred, Rachel continues to investigate the disappearance on her own, in the process raising the spectre of her dead marriage and the issues that led to its failure.
The story itself is well-written and, although I started to get an inkling of how things would shake out somewhere about 2/3 through the book, the final twist isn’t telegraphed and still managed to surprise me.
But none of these characters is likeable. Except one. Rachel, the ex-husband, the new wife, the husband of the missing woman, all of them were simply awful. The only person who seems to have any compassion and goodness of character is Rachel’s roommate, who is treated shabbily and still shows Rachel kindness. And while that may make these people more realistic and human, it also makes them difficult to side with: even Rachel, who is her own worst enemy and manages to sabotage herself at every turn. (Having struggled through and overcome a substance abuse problem myself, I am predisposed to empathy for her; even so, I wanted to take her by the shoulders and shout at her more than once. If nothing else, she made me realize how incredibly patient and loving my loved ones were with me when I was in the throes of addiction.)
So, to sum up, a good story, an engaging story, but one peopled by unlikeable characters being unkind to each other. Such is the drama of the London suburb.
