Alcoholism
The Girl on the TrainAlcoholism is a force shaping Rachel Watson’s daily routines, relationships, and sense of self, not merely a background habit. Drinking brings immediate escape from loneliness and distress, but repeatedly leaves her with missing time, shame, and consequences she must face while sober. The narrative traces this cycle through neglected responsibilities, concealed unemployment, and decisions made under the influence, while preserving Rachel’s own awareness that understanding the pattern is not the same as having escaped it.
Pattern and Daily Consequences
Rachel’s drinking appears in ordinary, private routines as well as moments of crisis. On one evening, after learning that Cathy is out, she buys two bottles of wine. She intends to prepare a proper meal, but after drinking she loses track of what she has left in the kitchen; she wakes later to find that the meal has gone unattended. Ashamed and unsure what she is apologizing for, she waits until Cathy and Damien have gone to bed before opening the second bottle. She then watches television quietly and, feeling an acute need for contact, reaches out to Tom Watson. The episode links drinking not to celebration but to isolation, disrupted memory, and a return to a relationship she has difficulty leaving behind.
The pattern is also visible in Rachel’s repeated reckoning with what she may have done while drunk. She describes waking into a familiar sense of shame and trying to reconstruct the previous night. On one such morning, she discovers that she has emailed Tom after drinking for several hours. The message angers her when she reads it sober, and she fears that Tom could show it to Anna Watson or the police. Her distress is sharpened by the gap between the person she believes herself to be and the hostile, impulsive version of herself represented by the email. She considers drinking and taking painkillers to sleep through the day, but pauses at the door and contemplates apologizing instead. The narrative presents that hesitation as a moment of choice, not proof that the cycle has ended.
Isolation, Loss, and Self-Blame
Rachel connects the worsening of her drinking to the loneliness that followed her struggle with infertility. The births of children to her university friend Lara and a colleague became painful reminders of what Rachel felt she could not have; these feelings strained relationships and made ordinary social contact difficult. Tom Watson wanted to be a father but believed the couple could still have a good life without children. Rachel experienced that difference as a failure of understanding: to her, it was possible to grieve for something never possessed.
She describes becoming lonelier as she drank more, since other people did not want to be around a drunk. Her account is not a simple explanation that makes infertility the sole cause. Rachel explicitly refuses to attribute all her drinking to childhood or tragedy: she says she had always liked drinking, while acknowledging that sadness deepened the problem. She distinguishes between being someone who drank and becoming a drunk, marking a change in how drinking organized her life. Her self-accountability coexists with harsh self-judgment: she measures her worth through beauty and motherhood, and concludes that she has failed at both. The novel shows that judgment as part of her distress, rather than treating it as an objective measure of her value.
Work, Concealment, and Public Judgment
Alcoholism undermines Rachel’s working life and encourages her to hide its consequences. She has lost her job at Huntingdon Whiteley after being drunk at work, but initially conceals both her unemployment and its cause from Cathy, who is also her landlady. Rachel worries that Cathy will fear for the rent and says she has some money and is trying to find another job. The concealment extends beyond a single explanation: Cathy later realizes that Rachel has been pretending to go to work, and confronts her about the sustained deception. Damien’s encounter with Martin Miles brings the false account into the open, leaving Cathy to ask where Rachel has been spending her days.
Rachel is also acutely conscious of being judged. She imagines that familiar passengers on the train may recognize her without seeing who she believes she really is, and interprets another passenger’s glance at her wine as distaste. Cathy’s concern that Rachel is lonely is met by Damien’s dismissive assessment of her prospects for companionship. These moments place her private dependence within a social world where drinking is visible and invites rejection. Rachel’s sensitivity to that judgment does not prevent her from drinking; instead, shame and concealment become further parts of the cycle.
Impaired Judgment and Unreliable Memory
The narrative links Rachel’s alcohol use to gaps in memory and uncertainty about her own actions. She recalls a night when she called Tom and remembers that her appeal to speak with him was more emotional than she had first admitted. The memory returns as a flashback while she is looking from the train, making the past feel at once newly accessible and painful. Elsewhere, she reconstructs episodes from what other people tell her: after a party, Tom described her behavior and said that her conduct had made him ashamed to go out with her. Such recollections make her account of herself unstable, but they also show her trying to distinguish what she remembers from what she has been told.
Drinking also compromises Rachel’s efforts to investigate Megan Hipwell’s disappearance. After deciding that she should accept her limited part in the matter, she drinks and contacts Scott Hipwell with a fabricated connection and a claim that she has information. Sober, she recognizes that the lie was intended to persuade him to talk to her. She describes the intoxicated version of herself as acting without regard for consequences, moving between excessive optimism and hostility. This self-description helps explain the lie without excusing it: Rachel sees how alcohol narrows her attention to the immediate desire to be involved, while leaving her to manage the consequences afterward.
Attempts to Change and Narrative Significance
Rachel does show signs of trying to change. She has read books and articles about coming to terms with infertility and considers sobriety necessary to the possibility of adopting a child. At one point she notes that she has gone three days without drinking, then tells herself she will begin again that day. The phrasing is cautiously hopeful, but the surrounding pattern makes clear that short periods without alcohol have not yet become lasting recovery. The evidence does not establish that she achieves sobriety.
Alcoholism therefore shapes both what Rachel does and how the reader receives her account. Lost time, remorse, and the difference between sober intentions and intoxicated conduct make her narration difficult to treat as consistently reliable. Yet the same narration records her attempts to identify the pattern, acknowledge her responsibility, and consider alternatives. The tension is central: Rachel can name the damage and still return to drinking, while moments of clarity offer possibility without guaranteeing change.
