Paula Hawkins book has gotten the film treatment and after reading it, I wonder if the story was written with that in mind. In the intro chapter, she even notes that viewing the scene from the train is like a tracking shot. Plus it’s got gorgeous blondes, drunken ex-wives, and lots of gory bloody violence. Rachel is the drunk who continues to ride to London on the morning train, pretending to go to work so her roommate doesn’t suspect that she’s lost her job. The train always stops at a crossing near her old house, the one where her ex-husband and new wife and child now live, and Rachel daydreams about a blonde couple she spots a few doors down, making up stories about their life as she chugs her gin & tonics on the train.
Then, a blackout drunk evening where she’s attempting to confront Tom, her ex, and the neighbor blonde goes missing while Rachel wakes up with a nasty gash on her hand, covered in blood. She goes to the police to tell them that she saw the neighbor (Megan) snuggling up to a man not her husband the Friday prior to her disappearance, which leads them on a chase to investigate her therapist, who’s later cleared. Then the police spotlight is on the husband, who while violent, isn’t the one who did it. Finally Rachel remembers enough from her blackout to implicate Tom, confronts his wife about it (who has discovered the dead girl’s phone in Tom’s gym bag), and the two of them are held hostage by Tom while Rachel is beaten. She eventually thrusts a wine opener into his neck (too preciously perfect a detail, n’cest pas?) and kills him.
