Chapter 13: The Murder of Judd Dodge and the Unmasking of a Killer?
⚠️ Spoiler Warning: This guide contains detailed spoilers for the entire novel. Proceed only if you've finished reading or are comfortable knowing the plot.
Summary
Judd Dodge collapses and dies from poison after drinking a martini. The other passengers are shocked, but Anna quickly deduces murder. She suspects one of the six guests or Seamus or herself. Anna examines the glass, finds a gritty residue and a chemical smell, confirming poison. She reconstructs the drink order: Dante mixed the drinks at the bar, guests chose glasses randomly, and Judd took the last one. Anna theorizes the poison may have been on the glass itself, not in the drink. She orders everyone to empty pockets and be frisked. Herb, Lapsford, Dante, Sal, and eventually Edith submit. During Edith’s search, the former nanny whispers “Schatzi” and needles Anna about her parents, triggering Anna to choke Edith. Seamus pulls her away. Edith has no poison container, nor does anyone else. Anna insists the killer is among them and declares no one leaves until a confession. After twenty minutes of silence, footsteps are heard, the door opens, and a ninth passenger—a man in a gray flannel suit—steps into the lounge.

Character Development
Anna – Her composure fractures. Although she avoids showing emotion, Edith’s provocation makes her physically attack the woman she once loved. Anna’s plan to force confessions is derailed by Judd’s death, and she must now pivot from orchestrator to investigator. Her internal conflict between hatred and lingering affection for Edith is exposed.
Edith – The former nanny shifts from passive observer to active manipulator. By calling Anna “Schatzi” and invoking her parents, she deliberately wounds Anna, revealing a cruel streak beneath her grandmotherly facade. She refuses to be searched voluntarily, forcing Anna to handle her.
Dante – Remains charming and calculating. He uses his nickname “Annie” to unsettle Anna and cooperates with the search while displaying a gleam that reminds Anna of their past. His quick logic about the random glass selection helps clear himself of immediate suspicion.
Seamus – Acts as Anna’s enforcer, conducting the searches and physically restraining her when she attacks Edith. He serves as both ally and anchor, urging her to stay in control.
Sal (Sally Lawrence) – Defensive and quick to accuse others. She points fingers at Edith and treats the search as an indignity. Her presence continues to trigger Anna’s memories of betrayal.
Herb Pulaski – Nervous and easily flustered, he wipes his brow and twists a handkerchief. He admits he and Judd were alone in the lounge first, making him a potential suspect.
Jack Lapsford – Pompous and resistant to the search, he eventually complies. His observation of the fingerprint smudge is critical to Anna’s theory.
New Passenger (Unnamed) – The chapter ends with the arrival of a ninth person, shattering the assumption that only eight people are aboard.
Themes, Symbols, and Motifs
Poison as Betrayal – Poisoning is a clandestine, intimate method of killing; it mirrors the hidden betrayals that define the group’s history. The killer struck without warning, much like the secrets each passenger carries.
The Glass as a Vessel of Intent – Whether the poison was on the glass or in the drink becomes a central puzzle. The glass symbolizes how easily an object can be turned into a weapon, and how a single smudge—a fingerprint—can be a clue or a red herring.
Loss of Control – Anna’s plan was meticulously crafted, but Judd’s death shows her control is an illusion. Her violent outburst with Edith demonstrates that even the most disciplined avenger can be overwhelmed by emotion. “Don’t flinch” becomes a mantra she fails to follow.
Memory vs. Present Reality – Anna’s recollection of loving moments with Edith and Sal clashes with her current hatred. The tension between past affection and present enmity drives her emotional volatility.
Why This Chapter Matters
Chapter 13 is the turning point where Anna’s revenge scheme derails. The murder of Judd Dodge introduces a second layer of mystery: not only are the passengers guilty of past crimes, but one of them is now an active killer. Anna’s role shifts from puppet master to detective, and her psychological vulnerability is exposed. The appearance of a ninth passenger at the very end reopens the question of who else is on the train and what their agenda might be. This chapter sets up the central whodunit for the remainder of the novel.
Study Questions and Answers
1. What evidence leads Anna to conclude that Judd was poisoned?
Anna notices a gritty residue inside the martini glass and smells a sharp chemical odor, which differs from a normal martini. She deduces someone added a toxic substance.
2. Why does Anna believe the poison may have been on the glass rather than in the drink?
Dante mixed all martinis in the same shaker and poured identical amounts into each glass. If the drink were poisoned, the other passengers who drank from the same batch would also have died. Since they did not, Anna hypothesizes the poison was applied to the inside rim of the glass Judd used.
3. What causes Anna to lose control and choke Edith during the search?
Edith deliberately calls Anna “Schatzi” (a term of endearment from Anna’s childhood) and then says Anna’s parents would weep at the person she has become. The combination of intimacy and accusation triggers a blinding rage in Anna.
