Part 2, Chapter 15 Summary

On January 8, 1951

London, England


Rosalind arrives at the Biophysics Research Unit at King’s College, London, having left Paris after discovering Jacques Mering’s deception. She unfavorably compares The Thames to the Seine and misses Paris. Professor John Randall, head of the unit, gives her a tour and explains what her role will be in the unit. Rosalind is shocked to learn that she will be using X-ray crystallography to study DNA rather than crystals. She has no background in this area and feels an immediate sense of anxiety. Randall does not put her at ease, especially when he responds coolly to the kind of quick humor that had been so common in her lab in Paris. She realizes that she will have to re-adapt to British culture and an entirely different working environment. Randall then introduces her to her new doctoral student, Raymond Gosling. He welcomes her to the unit, calling it a “circus,” and Rosalind wonders what she has gotten herself into.

Part 2, Chapter 16 Summary

On January 13, 1951

London, England


Rosalind hosts her parents and her brother, Colin, and his wife, Charlotte, for dinner in her new Chelsea flat. Her father, Ellis, dislikes the French dish Rosalind has prepared, but Colin and his wife both enjoy it. Although Rosalind is not entirely happy to be back in London, she is pleased at the growing sympathy between her and Colin. He often takes her side when conflict arises with their father. Ellis objects to more than the cuisine: He also questions the value of Rosalind’s career compared with family, faith, and the kind of philanthropic work he would prefer her to be doing. Rosalind defends her research, explaining that she studies the mechanism of life and genetic inheritance. She invokes Erwin Schrödinger’s interdisciplinary views to state her commitment to her scientific purpose.

Part 2, Chapter 17 Summary

On January 30, 1951

London, England


Rosalind and Ray discuss their experimental design in the lab. They are both excited, and he begins to speak informally, praising their work. He immediately apologizes for his use of the word “bloody”, but Rosalind explains that she is used to a French lab in which cursing is common, and people often let out whoops of joy when the work goes well. She adds that he also shouldn’t treat her any differently because she is a woman. He quickly explains that it wasn’t because of her gender that he apologized but because she is so “posh.” Rosalind is taken aback; she hadn’t been aware of a class difference between them. She assures him that she doesn’t think of herself that way and that they can speak informally together. Getting back to their work, they agree they need clear, multi-angle X-ray images and controlled humidity to solve the structure. A man bursts in and introduces himself as Maurice Wilkins, the unit’s assistant director. He speaks in a presumptuous tone and seems territorial about the lab. He addresses Rosalind as “miss” rather than “doctor,” and she takes an instant disliking to him.

Part 2, Chapter 18 Summary

On February 8, 1951

London, England


Gosling tells Rosalind he previously worked on the DNA project with Wilkins, which surprises her, as Randall had presented the assignment as hers alone. She reflects that a man of Wilkins’s education and experience should have been able to solve the problem that she has been hired to work on. She is irritated to have been misled so much about the nature of this job and about who her real colleagues would be. Later, Wilkins appears, offering unsolicited help on the project. She declines, and he appears angry and offended. At lunch, Wilkins steers his male colleagues to the all-male dining room, forcing Ray to choose. Rosalind tells him to go with them and eats alone. Once again, she is working in a British lab in which she is isolated and undervalued.

Part 2, Chapter 19 Summary

On March 23, 1951

London, England


Rosalind and Ray compare X-ray photographs taken at different humidity levels and discover two distinct DNA forms. She names the dry, crystalline pattern the A form and the wet, paracrystalline pattern the B form. They are elated at their discovery, and Rosalind invites Ray to the dinner she is hosting the following evening. There, her friend, Freda, warns Rosalind that she overheard Wilkins angrily confronting Randall about her. Wilkins believed Rosalind was hired as his assistant and wonders why she is attempting to take a lead role in their research. Randall, Freda explains, never corrected the misunderstanding.

Part 2, Chapter 20 Summary

June 30, 1951

Uppsala, Sweden


At a conference, Rosalind is happy to run into her former colleague, Vittorio Luzzati. He tells her that everyone at the labo misses her, even Jacques. Not wanting to discuss her former lover, Rosalind quickly proceeds to an account of her recent discoveries: The DNA has two forms and appears to be a helix. She also shares her strained relationship with Wilkins and the misunderstanding about her having been hired to work as his assistant that the lab’s head failed to clarify. Vittorio concludes Wilkins resents that a woman has succeeded where he failed and will try to take credit for her work. He advises her to share data sparingly and remain guarded about her findings.

Part 2, Chapter 21 Summary

July 24, 1951

London, England


Rosalind attends a conference at the Cavendish Laboratory in Cambridge. She compares it unfavorably to the conference she attended in Uppsala but does enjoy the chance to hear about other scientists’ new research. At one point, Rosalind sees Wilkins talking animatedly with Cavendish researcher Francis Crick. During a subsequent session on DNA, Wilkins presents Rosalind’s preliminary data without permission and announces that the observed pattern points to a helix. Afterward, Rosalind confronts him: The data is not yet ready to be presented, and he did not obtain her permission before sharing it at the conference. She asserts her authority over this project, which she was led to believe would be hers, and demands he stay away from her research.

Part 2, Chapter 22 Summary

On August 13, 1951

London, England


Rosalind returns to King’s after a holiday in Brittany. While there, a friend suggested to her that her manner of speaking to people is overly brusque, and Rosalind has been contemplating this assertion. On her first day back at the lab she finds a note from Wilkins proposing “collaboration” and a copy of a letter he sent to Crick sharing her data. She is furious that Wilkins would have the nerve to suggest they collaborate on her project. She is even angrier when she learns from Ray that Linus Pauling has also requested her DNA images. Happily, Randall refused him, but Pauling’s request only adds to her feeling that her authority is being undermined, almost certainly because she is a woman. Rosalind confronts Wilkins, with all of the “brusqueness” that her friend found so objectionable. She accuses him of trying to usurp control over her project and of misrepresenting it to other members of the scientific community. She informs him that science should be a slow, measured process and not a race and then slams the door in his face. From the expression in his eyes during their confrontation, she can see that he was shocked and offended.

Part 2, Chapter 23 Summary

On August 13, 1951

London, England


That evening, Rosalind attends a dinner at her brother’s home. She shares her troubles with Colin and his wife, Charlotte, explaining that Wilkins is trying to seize control of her project and that it is especially difficult for her to assert her authority over the research because she is a woman. In part because Wilkins frames his “coup” as a collaboration and in part because male scientists are apt to place more stock in men’s than women’s experiences, it has been difficult for her to find anything concrete about Wilkins’s behavior to report to her superiors. Colin and Charlotte are sympathetic, and Colin urges her not to let Wilkins wrest control over her research.

Part 2, Chapter 24 Summary

October 25, 1951

London, England


Randall convenes a meeting to settle the conflict. He confirms he gave Rosalind exclusive authority over the DNA X-ray crystallography work and rebukes Wilkins for misrepresenting both his role in Rosalind’s project and Rosalind’s ability to interpret her own data. He formalizes a division of labor: Rosalind keeps the superior Signer DNA sample, while Wilkins is assigned a different one. Wilkins leaves furious, and Rosalind feels her authority is finally secure.

Part 2, Chapter 25 Summary

On November 21, 1951

London, England


Wilkins retaliates by isolating Rosalind and enlisting his office mate, Bill Seeds, to harass her with pranks. Wilkins is also increasingly difficult in his interactions with Ray, and Rosalind feels badly that her sour relationship with Wilkins is affecting her graduate student. Ray shares that Wilkins has been spending time at the Cavendish with Crick and his young American partner, James Watson. Rosalind wonders what to make of this development but is sure that the three will ultimately band together and try to cut her out of her own research. At a colloquium, Rosalind presents her discovery of the A and B forms and states her data indicate a helical structure. Her fellow scientists are excited, but Rosalind worries that her authority over her own work is now even more imperiled.

Part 2, Chapter 26 Summary

December 4, 1951

Cambridge, England


The entire King’s team is summoned to the Cavendish. This request is unusual, and both Rosalind and Ray are initially confused. At the lab, Crick and Watson reveal a DNA model they built using information from Rosalind’s talk. Rosalind immediately spots fatal flaws in their discovery. She asks if they began their work with a specific conclusion in mind, and is puzzled when they answer in the affirmative. Surely, experienced scientists would understand that the scientific method requires scientists to begin with a hypothesis rather than a conclusion. She additionally points out that their three-chain helix fails to account for water. She points out the errors in their work without offering her solutions to them. She has no intention of sharing information that might help them solve the mystery of DNA before she does.

Part 2, Chapter 27 Summary

December 28 and 29, 1951

Paris, France


The mood at King’s has become fraught and competitive, and Rosalind is happy to spend the Christmas holidays in Paris rather than at home in London. She and Adrienne catch up, and Adrienne warns her against spending time with Jacques during her stay in Paris. Rosalind is also happy to see Vittorio. She shows her latest DNA photographs to Vittorio him, and he confirms the B form’s pattern signals a helix. He advises her to perform Patterson calculations before building a model. When she describes the flawed Cavendish model and Wilkins’s ties to its builders, Vittorio concludes Wilkins is leaking her data to the Cavendish team. He urges her to publish her work and leave King’s as soon as possible.

Part 2, Chapter 28 Summary

March 6, 1952

London, England.


Rosalind returns to London after the holidays and devotes all of her time to research. She knows that she must finalize her work as quickly as possible. Randall finds Rosalind in the lab one evening and asks her to prepare a preliminary report for an upcoming Medical Research Council meeting. Rosalind is not sure that she is ready, but from Randall’s tone and careful language, she can tell that his request is actually an order. Randall adds that Wilkins has given him an ultimatum: He will not work on DNA as long as she remains at King’s. Randall denies wanting her to leave but says they must find a resolution. Rosalind is not entirely sure that Randall’s denial is honest, and she knows she must tread carefully going forward.

Part 2, Chapters 15-28 Analysis

The novel uses laboratories to represent competing social and intellectual paradigms, contrasting the egalitarian environment of Paris with the rigid, patriarchal hierarchy of King’s College. Rosalind’s arrival in London is marked by a sense of displacement that mirrors the cultural dissonance she encounters. The King’s College Biophysics Research Unit is a physical manifestation of this fractured environment: a “hodgepodge of rooms” (88) in a building scarred by war. This fragmentation prefigures the social disunity within the unit. The college’s history and its “very maleness” (89) define it as an exclusionary institution, contrasting with the collegial atmosphere of the Parisian labo. This juxtaposition becomes especially evident when Wilkins leads his male colleagues to the all-male dining room, forcing Rosalind to eat alone. The laboratory at King’s is not merely a setting but a symbol of an institutional culture that fosters The Isolation of Women in the Sciences.


Maurice Wilkins embodies the sexism and patriarchal entitlement Rosalind must contend with. Their introduction is fraught and combative: He enters her lab without position, presumes a leadership role in her project, and addresses her disrespectfully rather than with the proper honorific “doctor.” This encounter is a fundamental personality conflict: Wilkins views the sciences from a masculinist perspective and, as such, he perceives himself as a “natural” authority and Rosalind a subordinate. Rosalind is self-assured and self-aware and does not doubt her own expertise. His actions consistently reinforce this dynamic, and their difficulties escalate from condescension to professional sabotage. He repeatedly attempts to insert himself into her research, misrepresents her work to outsiders, and ultimately presents her preliminary findings without consent. These actions are driven by a proprietary resentment, as he believes Rosalind was hired as his assistant and cannot accept that she is succeeding where he failed. Professor Randall’s ineffectual leadership amplifies this conflict through his failure to clarify Rosalind’s leadership role on the DNA project. The dynamic between them thus transcends personal animosity, representing a broader ideological clash between gendered privilege and expertise.


The narrative structure reinforces The Conflict Between Scientific Integrity and Personal Ambition through its depiction of the “scientific race.” Professor Randall introduces this concept upon Rosalind’s arrival, framing her research not as a pure pursuit of knowledge but as a competition. Randall, like many of his male colleagues, prioritizes speed over rigor. Wilkins fully internalizes this competitive ethos and because of it sacrifices his professional ethics. His premature presentation of Rosalind’s data and his unauthorized sharing of her findings are driven by ambition rather than a genuine interest in the science. Rosalind opposes this philosophy. Her process is characterized by patience, precision, and an insistence on accumulating irrefutable evidence. The ideological clash culminates in her confrontation with Wilkins after he attempts to co-opt her project, where she declares, “you forget that this is science, not a race” (145). This statement articulates the core tension between a methodical search for truth and a competitive rush for priority.


The novel consistently contrasts evidence-based discovery with speculative model-building, using the X-ray photographs as a symbol of objective truth. Rosalind’s entire methodology is oriented around producing a perfect, unambiguous image. Her painstaking efforts, from designing a new microcamera to mastering humidity control, represent a deep reverence for empirical evidence. The photographs, particularly the distinct patterns of the A and B forms, are not just data points but revelations of a hidden order. This methodical approach sharply contrasts with the efforts of Crick and Watson, who, inspired by Rosalind’s talk, hastily construct a three-chain model. Their process is one of theoretical conjecture, not empirical validation. Rosalind’s critique of their model is a display of scientific rigor; she identifies its fatal flaws not through opinion but through her knowledge of physical chemistry, specifically its failure to account for water content. Her decision to pursue time-consuming Patterson calculations rather than rush to build her own model underscores her commitment to letting the data lead, showcasing her commitment to scientific rigor in a field increasingly dominated by men who would sacrifice precision to win “the race.”


Relationships remain important as Rosalind navigates an increasingly hostile workplace environment. Although almost all of her colleagues at King’s dismiss Rosalind’s expertise because of her gender, her assistant Ray becomes a real collaborator and a genuine friend. He does respect Rosalind’s knowledge and her precise, methodological approach to research. The two bond initially over their shared commitment to scientific rigor and quickly develop a meaningful affinity. Rosalind’s friendship with Ray becomes a subtle counterpoint to the argument that Rosalind is difficult, “brusque,” and hard to collaborate with. Relationships like the one Rosalind has with Ray become a window into her real personality and help her to emerge complex, multi-faceted, and fully formed. This kind of characterization is especially important in light of her portrayal in Watson’s memoir, The Double Helix, a text that has become the “authoritative” account of the early days of DNA research.
