Summary

Jean Swinney arrives at Number 7, Burdett Road, Sidcup, a 1930s row house kept in noticeably better condition than her own. She pauses on the doorstep, resolving to buy Brasso on the way home, before ringing the bell. Mrs. Tilbury answers, a slender woman of about thirty with dark curly hair, holding a duster and rubber gloves. After a slightly awkward introduction, Jean is led into a front parlor that smells of wax polish and feels unused, saved for best.

Over tea, Mrs. Tilbury explains her situation. She is Swiss, from the German-speaking part of the country, though she has lived in England since she was nine. Jean notices her nervousness—her hand shakes as she pours. When Jean asks about the birth of her daughter, Mrs. Tilbury reveals that shortly before her nineteenth birthday she went to a doctor feeling tired and with aching breasts, and was told she was pregnant. She insists she had never even kissed a man. The doctor dismissed her claim, saying the manner of conception was not his concern and that her surprise did not change the fact that she was expecting.

Mrs. Tilbury's father was already dead by then; her mother believed her without question. Crucially, at the time of the supposed conception, Mrs. Tilbury was bedridden for four months at St. Cecilia's Nursing and Convalescent Home, being treated for severe rheumatoid arthritis, sharing a ward with three other young women. She learned of her pregnancy on November 1st, 1946, and Margaret was born on April 30th, 1947—late, not premature.

Jean is struck by this corroborating detail and admits to herself that she wants the story to be true, for reasons beyond journalistic hunger. The two women discuss intimate matters—Mrs. Tilbury's irregular menstrual cycle, her decision to keep the baby, and her mother's devout Catholic faith, which held that the child was a gift from God. Mrs. Tilbury says she never considered adoption.

Margaret arrives home from school, a girl of about ten in a green gingham dress and straw hat, flushed from the heat. She asks about kittens at a friend's house, then eyes Jean suspiciously and asks if she has ever met Queen Elizabeth. Jean admits she has not, but mentions meeting Harold Macmillan when he was elected MP for Bromley—a name that means nothing to the child. Jean is struck by the extraordinary resemblance between mother and daughter, seeing in Margaret a faithful reproduction of the pretty child Mrs. Tilbury must have been. She borrows an old photograph of Mrs. Tilbury as a girl, imagining the two images side by side in the paper.

The conversation continues. Mrs. Tilbury explains that her rheumatoid arthritis symptoms have almost disappeared since Margaret's birth, though she still wears bandages when hand-sewing causes stiffness. She works as a dressmaker, doing alterations, repairs, and made-to-order garments including wedding dresses. Jean, whose own needlework is rudimentary, admires this skill.

Jean asks whether Margaret knows about her origins. Mrs. Tilbury says Margaret knows her birth was special, and that while she calls her husband Daddy, she understands he is not her biological father—though he is her real father in every important sense. When Jean asks what Mrs. Tilbury hopes to achieve by pursuing the investigation, Mrs. Tilbury explains that she read the article in the paper and thought, “Yes! That's me!” She wants someone to prove what she has always known. Jean warns her that the paper, the scientists, and the public will be extremely skeptical, and that she will leave no stone unturned. Mrs. Tilbury says she has nothing to hide.

Jean asks about the husband. He owns a jeweler's shop on Bedford Street near Covent Garden and believes his wife absolutely. Jean takes down his name and number but has no intention of calling—she plans to turn up unannounced. She tells Mrs. Tilbury she will contact the geneticist who wrote the original article about parthenogenesis testing, and agrees to accompany them to London for the tests. Mrs. Tilbury seems relieved, as though depending on Jean as an advocate and protector. Jean feels the tug of friendship but resolves to resist it, knowing she may one day have to deliver unwelcome news.

Character Development

Jean Swinney reveals more of her inner life in this chapter. Her admiration for Mrs. Tilbury's beauty is tinged with envy—she describes her own figure as more like a grandfather clock than an hourglass. Her reaction to the doctor's dismissal of Mrs. Tilbury is visceral: “I despise doctors,” she says with more force than intended. She also thinks of her own mother and has to subdue a sudden surge of hatred, hinting at a difficult home life. Her professional instincts are sharp—she notices details, evaluates the room, and plans to visit the husband unannounced—but she also feels a personal pull toward Mrs. Tilbury's story. She wants it to be true, and she feels the tug of friendship, though she consciously resists it to maintain professional distance.

Mrs. Tilbury emerges as straightforward, genuine, and quietly brave. She answers personal questions without evasion, blushes at intimate topics, and expresses no fear of public scrutiny. Her motivation is simple: she wants proof of what she has always known. She is also a devoted mother, her face glowing with pride when Margaret enters the room. Her Swiss background and slight accent mark her as an outsider, a theme she acknowledges when she says, “We were already outsiders anyway.”

Margaret appears briefly but memorably. She is polite, curious, and suspicious of the stranger in her home. Her resemblance to her mother is so strong that Jean finds it disconcerting—evidence, perhaps, that no other man left a visible trace.

Themes, Symbols, or Motifs

Skepticism vs. belief is the central tension of the chapter. Jean repeatedly warns Mrs. Tilbury that her word will be doubted until proven true, yet Jean herself is already half-convinced. The doctor's refusal to believe Mrs. Tilbury stands in contrast to her mother's unquestioning faith.

Medical authority vs. personal testimony is explored through the doctor's dismissive treatment of Mrs. Tilbury. His certainty that she must be lying—or at least mistaken—is presented as a failure of both medicine and compassion. Jean's hatred of doctors suggests a broader distrust of institutional authority.

Motherhood and heredity are embodied in the physical resemblance between Margaret and her mother. Jean's observation that no other man has left a visible trace becomes a kind of visual evidence, however unscientific. Mrs. Tilbury's symptoms disappearing after Margaret's birth adds a mysterious, almost miraculous dimension to the mother-daughter bond.

Outsider status is explicit in Mrs. Tilbury's comment that she and her mother were already outsiders. Her Swiss accent, her foreign script, and her un-English beauty all mark her as different, even before the scandal of a virgin birth.

Domesticity and home are rendered in careful detail: the polished brass, the wax-polished parlor, the Alpine tapestry, the “Home Sweet Home” sampler. The Tilbury home is presented as a haven of order and care, in contrast to Jean's own neglected household chores.

Why This Chapter Matters

This chapter establishes the emotional and factual foundation of the novel's central mystery. Mrs. Tilbury's account is laid out in full, with the crucial corroborating detail of her four-month stay in a nursing home. Jean's decision to pursue the story—and her personal investment in believing it—sets the investigative plot in motion. The chapter also introduces the key relationship between Jean and Mrs. Tilbury, a friendship that Jean is determined to keep at arm's length but that clearly means something to both women. The reader is left with the same question Jean faces: is this a miracle, a medical phenomenon, or a hoax?

Study Questions and Answers

1. Why does Jean decide to visit Mrs. Tilbury's husband unannounced rather than calling him?

Jean takes down the husband's name and number but has no intention of using the telephone. She plans to turn up at his shop without warning. This reflects her investigative method: she wants to see his reaction in person, without giving him time to prepare. It also signals her determination to leave no stone unturned, as she told Mrs. Tilbury she would.

2. What evidence in this chapter makes Mrs. Tilbury's account more credible?

The most significant corroborating detail is that Mrs. Tilbury was bedridden for four months at St. Cecilia's Nursing and Convalescent Home at the time of the supposed conception, sharing a ward with three other young women. This makes it extremely difficult to imagine how she could have had any sexual encounter. Jean is visibly surprised by this revelation and admits she is glad, because it makes the claim harder to dismiss.

3. How does Jean's reaction to Mrs. Tilbury's story reveal her own character?

Jean wants the story to be true for reasons beyond journalistic ambition. She feels admiration and envy toward Mrs. Tilbury's beauty, a surge of hatred toward her own mother, and a tug of friendship that she consciously resists. Her decision to maintain professional distance shows self-awareness and discipline, but also hints at loneliness and a longing for connection that she is not ready to acknowledge.
