DeLisle

DeLisle is a wealthy-seeming but heavily indebted associate of Rupert Davenport whose proposed marriage to Isobel Davenport is revealed as part of a financial scheme, not a genuine courtship. Rupert had accepted payment for her, and the pair planned to use marriage to obtain control of her property and funds. DeLisle’s arrest for the alleged murder of his third wife brings the plot against Isobel into a wider reckoning over his debts and conduct toward women; before he can stand trial, he dies by suicide in custody.

Identity and Introduction

DeLisle first enters the account through the danger he poses to Isobel. Kitty has told Dominic Cavendish that Isobel was supposedly betrothed to him, leading Dominic and Isobel to infer that money had passed between DeLisle and Rupert. They suspect that Rupert expected to use Isobel to settle his debts and that DeLisle is angry because the arrangement has not delivered what he was owed. At this point, the financial bargain is an inference rather than a proven fact, but it establishes the terms in which the men appear to view Isobel: as payment and leverage.

Rupert later makes the threat explicit when he approaches Isobel. He presents DeLisle as a fiancé waiting to meet her, while Isobel firmly rejects any prospect of marrying him. Rupert warns that she cannot escape his control and invokes DeLisle as the man who will enforce her supposed place in life. The encounter makes clear that the proposed betrothal is backed by coercion, even before the men’s full financial arrangement is disclosed.

The Marriage Scheme and Financial Motive

When Rupert and DeLisle are confronted, Rupert admits that DeLisle paid him to make Isobel his wife. Rupert says he needed the money to hold off his creditors while he tried to secure Isobel’s signature on papers transferring the house and land. The marriage was thus meant to serve two connected purposes: DeLisle would obtain a wife in return for his payment, while Rupert sought access to property he could not otherwise claim.

DeLisle then explains the plan from his own side. After the marriage, he intended to persuade Isobel to transfer Gosport Hall and control of her funds. He says Rupert was to receive half of her worth as part of the payment arrangement. This disclosure confirms that the betrothal was not simply a personal alliance but a transaction designed to channel Isobel’s wealth between the two men. The proposed marriage would give them a means to seek control of her assets, although the evidence does not establish that they ever succeeded in obtaining them.

The scheme also reveals how the men’s interests differ. Rupert needs money to delay pressure from debtors and wants what he regards as his rightful inheritance; DeLisle expects a share of Isobel’s wealth and control over her finances. Their partnership is practical and conditional. When the plan is exposed, each turns on the other, with DeLisle accusing Rupert of greed and Rupert mocking DeLisle for being captured.

Conduct Toward Women and the Murder Case

Isobel describes DeLisle as a bully toward women and says his behavior with his wives had already raised questions. Her account informs the reader’s understanding of the danger in the proposed marriage, though it is distinct from the later legal evidence. DeLisle himself describes a plan in which, if Isobel had not become pregnant within six months, she would suffer the fate of his previous wives. His statement makes the marriage scheme threatening beyond its financial purpose, while the narrative does not depict the threatened harm in detail.

The case against him becomes more specific when Sebastian presents evidence collected against both men. It includes witness statements, records of debts to loan sharks and gaming houses, and accounts from two household staff members who say they saw DeLisle push his third wife down the stairs to her death. Sebastian identifies the deceased woman as Harriett Barnstable and announces an arrest warrant charging DeLisle with her murder. DeLisle denies killing her, maintaining that she fell. The accusation is therefore supported in the narrative by named witnesses and formal proceedings, while his denial remains part of the confrontation; he does not live to face a trial.

The financial evidence also widens the picture beyond the immediate arrangement with Rupert. Peter Davenport cites debts to moneylenders in London alongside allegations that Rupert removed Isobel from Willowbrook Hall without consent, imprisoned and assaulted her, and attempted Peter’s murder. Sebastian’s account adds DeLisle’s debts and the witnesses to his wife’s death. Together, these charges place the proposed marriage within a broader pattern of financial pressure and alleged violence, rather than presenting it as an isolated dispute over a betrothal.

Investigation, Exposure, and Death

Before the confrontation, Sebastian plans to go to London to investigate DeLisle and Rupert’s activities and financial position. His inquiries are part of an effort to establish what the men have been doing and to gather information relevant to their debts. Later, the evidence is presented directly to DeLisle, who challenges it, but the arrest warrant for Harriett Barnstable’s murder changes the encounter from an argument over Isobel’s future into a criminal proceeding.

As the men are taken from the room, Rupert and DeLisle exchange accusations rather than preserve their alliance. DeLisle denounces Rupert’s greed and the failure of their plan; Rupert answers by ridiculing him as he is led away. The collapse of their partnership exposes the self-interest beneath their apparent cooperation: neither offers loyalty once the other is vulnerable.

DeLisle struggles while being handled by Edward and shoots himself with Edward’s gun. Edward reports that the prospect of the gallows was too much for him. Dominic expresses no remorse for DeLisle’s death and turns attention to restraining Rupert and sending him to jail, so that he cannot evade justice as well. DeLisle’s death ends the immediate prospect of a trial and leaves the allegations against him without a verdict. It does not, however, erase what his own disclosures have established about the intended use of Isobel’s marriage, property, and wealth.

Narrative Significance

DeLisle’s role connects the threats against Isobel to a concrete financial motive. At first, the characters can only infer that a monetary bargain lies behind the supposed betrothal; the later confrontation supplies the terms, including the payment to Rupert and the planned transfer of Gosport Hall and Isobel’s funds. The revelation transforms a threatened marriage into evidence of a calculated attempt to gain control of her resources.

His separate murder charge broadens that revelation into a portrait of repeated danger. The witnesses’ account of Harriett Barnstable’s death, Isobel’s warning about his conduct toward his wives, and DeLisle’s own stated plan for Isobel place the proposed marriage within an alarming history. Yet the narrative preserves an important distinction between accusation and adjudication: DeLisle is arrested on a murder warrant, denies the charge, and dies before trial. His suicide closes his personal arc, while the exposure of his agreement with Rupert clarifies the stakes of Isobel’s resistance.
