Peter and Dominic's relationship

Peter Davenport and Dominic Cavendish’s relationship joins comradeship to chosen family: they face danger together, grieve together when they believe Isobel Davenport has died, and work in concert to protect her when she returns. Their friendship is expressed less through declarations than through coordinated action and mutual trust. Peter brings knowledge of Isobel’s family and legal position; Dominic’s love for her gives their common efforts a personal urgency. Once Isobel and Dominic marry, the friends’ bond also becomes one of kinship.

Comradeship and shared purpose

Peter and Dominic have a history of dangerous service that gives their friendship a practical foundation. They have gone to Norfolk together to help capture smugglers, and, once that business is concluded, return to Willowbrook Hall to find Isobel gone. Their common purpose soon turns from the mission to the search for her. Peter’s own experience of war is acknowledged by Isobel, while Dominic’s years in the army inform his habits of command; the two men meet threats as experienced allies rather than as strangers brought together by circumstance.

Their cooperation is not merely a matter of pursuing the same objective. When Dominic must leave Isobel at Willowbrook Hall to speak with Sir Hubert Williams, he asks her to avoid accepting any marriage offers while he is away. He is uneasy about leaving her in the care of Elspeth, but accepts Peter’s judgment that the two women can safely remain there. The request reveals the trust between the men: Dominic relies on Peter’s understanding of his family and on his ability to look after Isobel in Dominic’s absence.

Grief and the search for Isobel

At Willowbrook Hall, Peter and Dominic learn that Rupert Davenport had removed Isobel from Elspeth’s care under threat and deception. Elspeth had last seen her niece in a hurried, tearful farewell before she was taken away in an unmarked carriage. The news turns the men’s return from Norfolk into a search. Kitty’s account gives them a route to follow: she reports Isobel’s escape from Gosport Hall and her own eventual return to Willowbrook Hall. Rupert, meanwhile, has left to search for Isobel after learning she escaped.

Peter and Dominic search with the remaining staff, questioning people in towns and villages and combing the countryside as they move north. Their inquiry leads them to reports of an unidentified young woman found dead near Peterborough and buried in a village pauper’s grave. The burial has none of the family recognition or dignity Peter wants for his sister; a plain wooden cross marks the grave only because local sympathy prompted someone to provide one. In this moment, the friends’ shared investigation becomes shared bereavement. Both contemplate the possibility of murder without openly naming it, and Dominic struggles to contain the anger and grief the supposed death has brought.

The necklace found on the body seems to settle the question for them. It is Isobel’s star necklace, given to her by her father on her tenth birthday and worn ever since. Its sentimental importance, rather than its monetary value, makes it persuasive evidence: both men believe Isobel would never have willingly parted with it. Their certainty is later confronted when Dominic shows the necklace to Isobel herself. Her response makes him suspect that she knows something about how it came to be on another body, but this encounter does not immediately give him an answer. The episode demonstrates how the friends’ loyalty is bound up with the evidence they can gather, and how that evidence can mislead them even when it appears intimate and conclusive.

Mutual care and Isobel’s return

Peter and Dominic’s friendship also provides Isobel with a place to speak about what the men’s absence and the false reports of their deaths meant to her. She tells Peter that she loved Dominic before he left for Norfolk and describes the grief caused when Rupert claimed that Peter had been killed and that Dominic had returned married to someone else. Peter, in turn, tells her that he and Dominic were devastated when they were led to what they believed was her grave. He stresses that Dominic’s anguish was especially severe after Dominic had spent weeks trying to return to her. Peter’s account makes clear that Dominic’s love was already central to their friendship’s most painful trial: Peter not only shares Dominic’s grief but understands what Isobel’s supposed death meant to him.

When Isobel is back with Dominic, the partnership continues through practical protection. After Dominic is injured, Peter leaves with several men to inspect the area, while Dominic’s brothers and others remain at the house, armed and keeping watch. Isobel reports Peter’s actions as part of the household’s security arrangements. Dominic, accustomed to command, resents being unable to take charge himself, but the response around him shows that Peter is acting as a trusted ally in a shared emergency, not simply as a relative intervening on Isobel’s behalf.

Kinship, law, and lasting loyalty

Peter’s family knowledge becomes especially important when Rupert and Bertram DeLisle challenge Isobel’s marriage to Dominic. Rupert claims that Isobel is already DeLisle’s wife and uses documents to make Dominic doubt her. Peter steps between the opposing men and asserts that he was Isobel’s legal guardian when the supposed marriage took place and never gave permission for her to marry DeLisle. He identifies an older set of papers, signed and witnessed by magistrates, recording Isobel’s betrothal to Dominic years before Rupert’s claim. Peter’s intervention turns their friendship into an alliance with direct legal and familial stakes: he uses his authority and evidence to defend both Isobel’s freedom and Dominic’s marriage.

The relationship’s decisive change is therefore not a break in their friendship but its enlargement. Peter trusts Dominic with Isobel’s safety, recognizes the depth of his love for her, and supports the marriage against Rupert’s attempted deception. Isobel’s marriage makes Dominic Peter’s brother-in-law, giving formal kinship to a bond already tested by a dangerous mission, a fruitless search, an apparent bereavement, and a united defense of her future. Their loyalty does not prevent fear or uncertainty, but it gives each man a dependable ally as the crisis changes shape.
