Book of the Year 2015. A novel that has dominated all bestseller charts on both sides of the Atlantic, breaking records for sales speed and being labeled by critics as this year's Gone Girl. Need to know more? Rachel commutes to London on the morning train. Day after day, she gazes at cozy suburban houses, and when the train briefly stops at a signal, she regularly catches a glimpse into the private life of a young couple. Over time, Rachel begins to feel that she knows these two people. She imagines that she knows them. She even gives them names: Jason and Jess. One day, however, she sees something that shocks her. It only takes a minute before the train starts moving again, and suddenly everything is different... Shortly thereafter, Rachel learns that 'her' Jess is missing, and she decides to contact the police. She is unsure if she will cause more harm than good, while becoming increasingly entangled in a story that is not hers, but which ultimately turns everyone's life upside down...
