Read the Full & In-Depth Chapter-by-Chapter Summary of The Girl On The Train Book
Rachel Watson takes the 8:04 slow train from Ashbury to Euston every weekday. She is not actually going to a job. She drinks gin and tonics to cope with the end of her marriage to Tom and the loss of the life she wanted.
From the train, she watches a couple at number fifteen Blenheim Road. She names them Jess and Jason. To Rachel, they look like the perfect couple, and she becomes obsessed with their imagined life.
One Friday in July, Rachel sees Jess kissing a man who is not Jason. The sight feels like a personal betrayal. The next day, Rachel learns from the news that Megan Hipwell, the woman she calls Jess, has disappeared.
Rachel was in Witney that night, but she drank so heavily that she has a total blackout. She wakes with a head injury, blood on her clothes, and no memory of what happened. She decides to contact Megan’s husband, Scott, and pretends to be a friend of Megan’s.
Rachel tells Scott and the police about the kiss. Her information points to Megan’s therapist, Dr. Kamal Abdic. The police briefly arrest Kamal, but they release him without enough evidence.
Flashbacks from Megan’s perspective reveal that she was restless in her marriage to Scott. She had an affair with Kamal and, before that, a relationship with Tom Watson when she worked as a childminder for Tom and Anna’s baby.
Rachel eventually recovers pieces of her memory. She realizes Tom spent years gaslighting her and making her believe she committed violent acts during her blackouts. She also remembers seeing Megan get into Tom’s car on the night Megan vanished.
Megan’s body is found in Corly Wood. She was pregnant with Tom’s child. Tom took her there and killed her by crushing her skull with a rock when she threatened to tell Anna.
Rachel goes to Tom’s house to warn Anna. Tom returns, confesses under pressure, and attacks Rachel. In the struggle, Rachel stabs Tom in the neck with a corkscrew.
Anna sees the struggle from the window and realizes how deeply Tom lied to her. Instead of helping him, she twists the corkscrew deeper into his wound and lets him die. Rachel and Anna tell the police it was self-defense.
Rachel leaves the area after being sober for three weeks. She is free from Tom’s control but remains bound to Anna by their shared secret.
