Teacher looks for: Clear links between Part 2’s backstory and Part 1’s clues, tone, and characters
How to meet it: Explicitly reference specific Part 1 events when discussing Part 2’s impact, using a two-column notes format to track connections
Teacher looks for: Analysis of Part 2’s role in developing the novel’s central themes, not just a summary of events

Part 2’s flashback structure serves two main goals: it explains the murder’s motives, and it challenges readers to reevaluate their initial assumptions. Without this section, the novel would be a simple detective story alongside a commentary on morality and justice. Use this point to lead your next class discussion on narrative structure.
Part 2’s American frontier setting creates a moral framework that’s very different from London’s Victorian legal system. The harsh, unregulated environment shapes the characters’ choices and justifications for their actions. Write one paragraph comparing these two moral systems for your essay draft.
Many essay prompts ask students to analyze the novel’s commentary on justice, and Part 2 is the key to answering this effectively. You can use Part 2’s backstory to argue that the novel critiques both frontier vigilantism and rigid legal systems. Highlight 2 specific events from Part 2 to support this argument in your next essay outline.
Another common mistake is overstating the killer’s heroism or villainy without nuance. The novel deliberately blurs these lines to explore moral complexity. Write a 2-sentence reflection on how Part 2 makes this blurring clear.
Quizzes may also ask about the novel’s thematic shift between parts. Practice explaining how Part 2 changes the novel’s focus from detective work to moral commentary. Write a 1-sentence answer to this question to use as a quiz cheat sheet.
Come to class with one discussion question that challenges peers to think about Part 2’s moral ambiguity. Use the discussion kit’s sentence starters to frame your question. Bring notes with one Part 2 detail to support your question if called on.
No, Part 2 is a flashback that directly explains the murder mystery introduced in Part 1. Every event in Part 2 ties back to the clues and characters from the first half of the novel.
You can follow the basic detective plot in Part 1 without reading Part 2, but you’ll miss the novel’s core commentary on justice and moral ambiguity. Part 2 is essential for full analysis of the story.
The setting shift from London to the American frontier highlights the contrast between two very different moral systems. This contrast is critical to understanding the killer’s motives and the novel’s thematic message.
The most critical takeaway is that the murder is a calculated act of retribution rooted in past trauma, not a random crime. This changes the way readers and characters perceive the killer and the crime itself.
