Chapter 22: Summary, Analysis, and Key Takeaways
⚠️ 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
The chapter opens in June 2019 with Samuel receiving a phone call from Saffron, who delivers the results of the textile fiber analysis that the forensic team has been conducting. Saffron reports that the fibers are cotton toweling, which strongly suggests that the body was wrapped in towels after death. More significantly, the fibers carry traces of blood and hair, offering potential biological evidence that could be linked to either the victim or the perpetrator. In addition, the lab has found a small shred of man-made fiber, likely part of a label from one of the towels. This fragment bears traces of printed text, though not enough to read full words. The lab is currently analyzing the fragment in the hope of identifying a brand, which could provide a crucial lead.
Saffron is visibly excited about the findings, describing herself as “pretty fucking ecstatic” about the combination of hair, blood, and a possible brand. Samuel, who normally dislikes swearing and finds it unpleasant to his ears, is so moved by the news that he agrees with equal enthusiasm, exclaiming his own profanity—a first for him. Saffron laughs at his uncharacteristic outburst, noting that she has never heard him swear before. Samuel admits that he has never felt the need until now.
Saffron tells Samuel that the lab is fast-tracking all the work and expects more updates within the hour. She tells him to “watch this space,” and Samuel replies that he is watching it “like a hawk.” After ending the call, Samuel checks to ensure he is not being observed, then punches the air with a fist—very gently—in a private moment of celebration.
The chapter is brief but pivotal, capturing a single moment of investigative momentum. The forensic results transform what might have been a stalled case into one with tangible leads: hair, blood, and a potential brand name. Samuel’s reaction reveals a depth of personal investment that he usually keeps hidden, and the chapter ends on a note of cautious hope.

Character Development
This chapter offers a rare glimpse into Samuel’s emotional interior. Throughout the novel, Samuel has been portrayed as reserved and meticulous, a man who values order and precision. His stated aversion to swearing is a small but telling detail: it suggests a fastidiousness, perhaps even a moral rigidity. Yet when Saffron delivers the forensic breakthrough, Samuel’s reaction breaks that pattern. He not only tolerates her profanity but echoes it with his own “Fucking amazing!” This is a significant moment of character growth, or at least a revelation of a deeper layer. The fact that he has “never felt the need” to swear before indicates that this case has affected him on a level that his usual composure cannot contain.
His private celebration—checking that no one is watching before punching the air—adds another dimension. It shows that Samuel is not merely a detached investigator; he is emotionally invested in the outcome. The gentleness of the gesture (“very, very gently”) suggests a man who is not accustomed to overt displays of emotion, but who allows himself a small, controlled release. This moment humanizes him, making his character more relatable and complex.
Saffron, though present only through dialogue, also displays a professional enthusiasm that contrasts with Samuel’s usual restraint. Her use of profanity and her declaration of being “ecstatic” underscore the significance of the findings. She is clearly a dedicated colleague who shares Samuel’s investment in the case.
Themes, Symbols, or Motifs
Forensic Science as Revelation: The chapter centers on the power of trace evidence to unlock hidden truths. Cotton toweling, blood, hair, and a label fragment are mundane objects, but in the context of an investigation they become keys to a larger story. The chapter emphasizes that even the smallest physical remnants can carry immense significance, a theme that resonates throughout crime fiction and real-world forensics.
Hope and Momentum: The chapter is suffused with a sense of renewed hope. The phrase “fast-tracking” and the promise of updates within the hour create a feeling of acceleration. Samuel’s celebratory gesture, though small, signals a shift from passive waiting to active anticipation. The motif of watching—Samuel says he is “watching like a hawk”—reinforces the idea that the investigation is now moving forward with purpose.
The Symbolism of the Towel: The towel is a loaded symbol. It is an object of domesticity and comfort, yet here it is used to wrap a body after death. This juxtaposition of the ordinary and the macabre highlights the unsettling nature of the crime. The label fragment, with its printed text, suggests the possibility of identification—a brand name that could lead to a purchase location, a store, or even a specific person. The towel thus becomes a bridge between the anonymous victim and the world of consumer goods, potentially linking the crime to a particular place or time.
Character as Motif: Samuel’s aversion to swearing is a recurring motif that the author uses to measure his emotional state. His breaking of this personal rule signals a turning point, not just in the investigation but in his own psychological journey. The motif of restraint versus release is echoed in his gentle air punch, which is both a physical and emotional release.
Why This Chapter Matters
This chapter is a turning point in the narrative. It provides the first concrete forensic breakthrough in the case, transforming a vague investigation into one with actionable leads. The combination of hair, blood, and a potential brand name offers multiple avenues for further inquiry: DNA analysis could identify the victim or the perpetrator, and the towel label could trace the towels to a specific retailer or even a specific purchase. The fast-tracking of the lab work suggests that the authorities are treating this case with urgency, raising the stakes for all involved.
On a character level, the chapter deepens our understanding of Samuel. His uncharacteristic outburst and private celebration reveal a man who is deeply affected by the case, perhaps more than he lets on. This humanizes him and makes his subsequent actions more meaningful. The chapter also sets up a cliffhanger of sorts: the promise of more updates within the hour leaves the reader eager to see what the lab will find next.
In the broader structure of the novel, this chapter serves as a bridge between the initial discovery of the body and the subsequent investigation. It injects a dose of optimism and momentum, reminding the reader that even in the darkest circumstances, science and persistence can yield answers.
Study Questions and Answers
1. How does Samuel’s use of profanity in this chapter contrast with his usual character, and what does it reveal about his state of mind?
Samuel explicitly states that he dislikes swearing and that it “bothers his ears.” His use of “Fucking amazing!” is therefore a deliberate departure from his norm. The fact that he feels the need to swear indicates that the news has overwhelmed his usual composure. It reveals that he is deeply invested in the case and that the forensic breakthrough has given him a surge of hope and excitement that he cannot contain. His subsequent private celebration—checking that no one is watching before punching the air—reinforces this interpretation, showing that he is emotionally affected but still cautious about displaying his feelings publicly.
2. What are the potential implications of the hair, blood, and label evidence for the investigation?
The hair and blood found on the cotton toweling could provide DNA evidence, which might identify the victim or the perpetrator, or establish a connection between them. The presence of blood suggests that the body was wrapped after death, but the hair could have come from either the victim or the person who handled the towels. The label fragment, if a brand can be identified, could lead investigators to the specific towels’ manufacturer or retailer, potentially tracing the purchase to a location or even a specific individual. Together, these pieces of evidence offer multiple investigative leads that could break the case open.
3. How does the author create tension and momentum in this short chapter?
The author builds tension through the delivery of incremental information. Saffron reveals the results in stages: first the toweling, then the blood and hair, then the label fragment. Each piece of information raises the stakes. The promise of more updates “within the hour” and the fast-tracking of the lab work create a sense of urgency. Samuel’s reaction—his swearing and his “watching like a hawk” comment—amplifies the emotional intensity. The chapter ends with a physical action (the air punch) that provides a release of tension while also leaving the reader eager to see what happens next.
