Rachel (Emily Blunt) is an alcoholic who is obsessed with an ideal couple she sees from the train each day. But one day, she sees the woman with someone else, someone not her husband. When, shortly after this, the woman disappears, she thinks she might know something, but her blackout drunkenness won’t allow her to remember it.
I enjoyed this book immensely, and I’m glad I let several years pass before watching the film. My memory of the plot was there, but not the final twists and turns, and so I could thoroughly enjoy every step of it. There’s some upsetting violence, but only what is appropriate to the story. I thought it was fantastic, a really good thriller.
