⭐ Why It Matters
The Girl on the Train is a masterclass in unreliable narration, hidden trauma, and suburban secrets. With a twisty, layered plot and emotionally complex characters, it keeps readers questioning what’s real until the final pages. Its global popularity and film adaptation have made it a modern benchmark in psychological crime fiction.
👥 Main Characters
- Rachel Watson – The titular “girl on the train.” An alcoholic, heartbroken woman who takes the same commuter train daily — and watches the lives of people she doesn’t know.
- Megan Hipwell – A beautiful young woman Rachel sees from the train window. Mysteriously disappears.
- Anna Watson – Rachel’s ex-husband’s new wife, now living in Rachel’s former home. Tense, guarded, and protective.
- Tom Watson – Rachel’s ex-husband. Seemingly supportive, but with a dark underside.
- Scott Hipwell – Megan’s husband, controlling and volatile. A key suspect.
- Dr. Kamal Abdic – Megan’s therapist, who may have had a personal connection to her.
📚 Plot Summary
🔹 Rachel’s Obsession
Rachel is unemployed, alcoholic, and pretending to commute each morning so her roommate won’t know she’s lost her job. From the train, she watches a couple (Megan and Scott) and imagines their perfect life.
When Megan suddenly goes missing, Rachel inserts herself into the investigation — believing she saw something important from the train.
🔹 Multiple Perspectives, Shifting Truths
The story is told through three unreliable narrators: Rachel, Megan, and Anna.
We learn about:
- Rachel’s blackout drinking and obsessive behaviour around Tom and Anna
- Megan’s troubled past involving loss and guilt
- Anna’s discomfort with Rachel’s ongoing presence and past instability
Rachel begins digging into the case, even contacting Scott and pretending to be a friend of Megan’s. As she tries to recover her memory from the night of the disappearance, she starts uncovering disturbing truths.
🔹 The Twist
Rachel remembers seeing Megan with another man — possibly her therapist, Dr. Abdic. But as more pieces fall into place, it’s revealed that the true danger was much closer to home.
Tom, Rachel’s ex, had been having an affair with Megan — and murdered her when she threatened to expose him. He had been emotionally manipulating both Rachel and Anna for years.
🔹 Ending – Justice, Finally
In a climactic confrontation, Rachel and Anna confront Tom. Rachel kills him in self-defence — with Anna delivering the final blow.
Though the ending is dark, Rachel reclaims a sense of identity and control, choosing to move on with her life.
