Isobel and Peter's relationship

Isobel and Peter’s relationship is a sustaining sibling alliance, made visible both in the practical protection they offer one another and in the painful truths they are willing to share. When Rupert separates them through a false report of Peter’s death, their bond becomes a means of survival: Peter seeks Isobel’s whereabouts, while Isobel later offers him the same determined support as he pursues the possibility of happiness with Jemima.

Family bond under threat

The rupture begins after Isobel has spent two and a half weeks with Elspeth. As Isobel recounts to Peter what followed, she remembers Elspeth distractedly talking over tea when Ellison admitted Rupert. He entered in a rage about being kept waiting, helped himself to the decanters, and announced that Peter had died and that he had come to remove Isobel as her guardian. Isobel recalls being most stunned by the supposed death of her brother; her distress becomes physical as she trembles too much to hold her teacup.

Rupert said that a magistrate named Worthing had informed him Peter died in Norfolk, and used that report to claim authority over Isobel. He ordered her to pack at once, saying he could not remain at Willowbrook Hall and would arrange for its disposal later. When Isobel protested that she should stay, Rupert called Elspeth unstable and threatened to have her sent to an asylum. Isobel agreed to leave only after extracting a promise that Elspeth could remain at Willowbrook Hall for the time being. Her account emphasizes how little room she had to act: she could not verify Peter’s death, was given little time to pack, and was ushered into a waiting carriage before she could understand what was happening.

Isobel nevertheless asserts a measure of control by refusing to go without Kitty. Rupert initially resists, but agrees when Isobel insists that she needs her maid and will not leave her behind. This small but consequential stand accompanies the larger story of separation: Isobel cannot prevent Rupert from taking her away, but she can insist on keeping a trusted companion with her. When she later tells Peter what happened, she gives him a detailed account of the coercion and fear that his supposed death had made possible.

Separation, memory, and return

The siblings’ family history is also bound up with Gosport Hall, a remote hunting lodge outside Northampton. Peter explains that their father inherited it and that it passed directly to Isobel after his death, although the family did little with the property while she was young. He and Isobel had often gone there as children; after their mother died, their father could not bear to return. Peter had almost forgotten the lodge, despite its belonging to Isobel and its significance as a former second home. In the present, its existence matters because it helps Peter and Dominic consider where Rupert might have taken her.

Their shared history does not erase the damage of the separation. Later, while Dominic is away, Peter remains with Isobel and notices her solemn attention to the fire and her unconvinced smile when he says her husband should be home soon. He tells her that he needs to return to Willowbrook Hall, explaining that he had stayed because he wanted to make sure she was happy. His concern is attentive rather than possessive: he observes that she has regained weight and that, despite her distress at Dominic’s absence, she seems quietly content in her married life. His observation gives Isobel’s recovery a witness in her brother, while her subdued mood shows that reunion with Peter cannot remove her longing for Dominic.

Isobel supports Peter’s hope

The care between them runs both ways. When Isobel learns that Peter still loves Jemima, she urges him to marry her if they find her and promises to continue the search after he returns to Willowbrook Hall. Peter is startled by how readily Isobel accepts his intention. He raises the prospect of family censure because Jemima was a servant, though he says she did not come from a background of service. He cannot bear the prospect of marrying a woman he does not love, or of closing off his affections for Jemima.

Isobel answers his concern with the knowledge of her own compromised position. She points out that her family might already face scandal if people learned she had lived as a pauper on the streets and spent her first month in a single man’s house, lying ill in the master suite. She also notes that Elspeth’s talk may have led members of The Ton to believe she was kidnapped by Rupert and married to DeLisle. By setting Peter’s feared social censure beside the risks already attached to her own reputation, she refuses to treat his love as an unacceptable exception. Her counsel is personal as well as practical: a family that has endured so much cannot make respectability the sole measure of who deserves happiness.

Isobel explains why she can recognize the pain of loving someone who may be out of reach. Before Peter and Dominic left for Norfolk, she already loved Dominic and prayed for their safe return, knowing they might not come back. Rupert’s claim that Peter had been slain deepened her grief; his further lie that Dominic had returned alive but married someone else made the loss feel worse. She does not present this history as a reason to withdraw from Peter’s troubles. Instead, she tells him that she will do whatever she can to help him and Dominic find and keep the happiness they deserve. Her promise turns sympathy into a shared undertaking, and she insists that Peter and Jemima’s whereabouts will be uncovered wherever they are.

Protection, testimony, and legal claims

Peter’s loyalty also takes a direct protective form when Isobel’s marriage is challenged. While writing, at Dominic’s request, an account of the events that drove her onto the streets, Isobel remembers a betrothal document she had previously forgotten. Rupert and DeLisle had tried to force her to sign a document naming DeLisle as her intended; she refused. Her recollection supplies an important piece of evidence, and the knowing looks exchanged by the men show that they understand the consequences of her resistance.

During the confrontation with Rupert and DeLisle, Peter places himself between them and Isobel, then asserts that he was her legal guardian when the alleged marriage took place and had not consented to any marriage except the one to Dominic. He argues that she could not have legally married DeLisle unless she had been forced, and cites papers, signed and witnessed by magistrates, recording her betrothal to Dominic three years earlier. This defense sits in sharp contrast to Rupert’s earlier claim that Peter’s supposed death made Rupert Isobel’s guardian. The relationship is therefore not only intimate and emotional: Peter uses his standing and documentary evidence to contest the authority invoked against his sister, while Isobel’s remembered testimony helps expose the attempted coercion.

A reciprocal alliance

Across the separation, the reunion, and the dispute over Isobel’s marriage, Peter and Isobel repeatedly act as witnesses to one another’s experience. Peter recognizes her recovery and remains with her while Dominic is away; Isobel trusts him with the story of Rupert’s deception and the depth of her grief. She then extends to Peter the hope she has found with Dominic, promising active help rather than merely offering comfort. Their bond is defined by this exchange: each sibling takes the other’s distress seriously and responds with protection, testimony, or practical assistance. Against false reports, family pressure, and threatened scandal, their loyalty becomes a source of agency neither can easily claim alone.
