Emily Inglethorp and Alfred Inglethorp

Emily and Alfred Inglethorp’s marriage becomes the central instrument of a plot that joins private betrayal to the legal and financial stakes of inheritance. Alfred benefits from the marriage’s effect on Emily’s earlier will, but the evidence eventually reveals that his apparent vulnerability and the suspicions directed at him conceal a conspiracy with Evelyn Howard. Emily, meanwhile, discovers evidence of that betrayal and tries to protect herself, though she does not understand how she is in danger.

Marriage, Inheritance, and Legal Stakes

Before marrying Alfred, Emily had made a will leaving her entire fortune to her elder stepson, John Cavendish, after certain legacies to servants. John explained that this arrangement was meant to be equitable: under his father’s will, John would inherit the property, while Lawrence Cavendish would receive a considerable sum when Emily died. John was expected to maintain Styles, giving Emily’s decision a practical basis as well as a financial consequence for the family.

That earlier will did not remain operative after Emily’s remarriage. Hercule Poirot drew attention to the rule that an English will was automatically revoked by remarriage, a point confirmed during questioning of Mr. Wells. The legal change made Alfred’s position appear consequential: he stood to benefit from Emily’s death, and, as Poirot later observes, her husband would benefit more than anyone else. But the rule also becomes part of the misdirection. John’s defense at trial emphasizes that Alfred, who had formerly practiced at the Bar, knew the earlier will had been revoked; Alfred therefore had reason to understand the legal situation without needing Emily to make a fresh will in his favor.

A New Will and a Sudden Reversal

On July 17, after a quarrel between Emily and John at about four o’clock, Emily made a new will in favor of Alfred. Two gardeners were called in to witness her signature. They signed at the bottom of the paper beneath her name, while blotting paper covered the text, so they did not see what the document said. The act briefly appeared to mark a decisive change in the distribution of her estate.

Poirot reconstructs a sharp reversal between the making of that will and Emily’s later wish to destroy it. At five o’clock, Dorcas found her mistress agitated, holding a slip of paper, and asking for a fire to be lit. Poirot reasons that Emily had gone to Alfred’s locked desk in search of stamps, using one of her keys that fitted it, and there found a letter never intended for her eyes. The paper, in Poirot’s reconstruction, disclosed Alfred’s perfidy and his alliance with Evelyn. Emily kept the letter, decided to write to her solicitor to come the next day, and resolved to destroy the new will. The destroyed document thus records not a simple settlement of her estate but the brief interval in which she changed her intentions, then discovered a reason to withdraw from the arrangement.

The Murder Conspiracy and Emily’s Discovery

The prosecution presents Emily as a trusting benefactress and Alfred as the stepson who poisoned her despite her long support of him and John’s household at Styles. Its account stresses financial strain, an alleged intrigue with Mrs. Raikes, the quarrel on the afternoon before Emily’s death, and the purchase of strychnine by someone disguised as Alfred. Alfred’s alibi, however, prevents that line of accusation from holding. Poirot initially considers the husband’s apparent motive, but also recognizes that the evidence against him has been made so conclusive that it may have been manufactured to clear him once disproved.

The final explanation identifies Alfred and Evelyn Howard as accomplices. Poirot says they were cousins and had a passionate attachment before Alfred came to Styles. Their plan, as he reconstructs it, was for Alfred to marry the wealthy Emily, induce her to make a will in his favor, and then secure the money through a carefully planned crime. The evidence of their private alliance reverses the meaning of Alfred and Evelyn’s public conduct: Evelyn’s conspicuous hatred of him was not proof of hostility but a cover for the opposite feeling. Emily’s discovery of the letter exposes the partnership, though a reference to bromides does not warn her of the actual danger.

The timing of the murder does not go according to plan. Poirot explains that the crime was intended for Monday evening, when Emily’s bell wire had been cut and Cynthia was staying away from home, leaving Emily isolated in the right wing. Emily forgot to take her medicine before going to a village entertainment, and the following day she lunched away from home; as a result, the fatal dose was taken twenty-four hours later than the conspirators anticipated. The delay gives Poirot the final link in the chain: three strips of a letter in the murderer’s handwriting, addressed to Evelyn. It confirms the correspondence behind the conspiracy and shows that Emily sensed danger without understanding its method.

Exposure and Significance

After Emily’s death, Alfred forces the lock of her despatch-case in an attempt to recover the letter. The risk of that act underscores its importance: apart from the incriminating document, Poirot says, there was nothing to connect Alfred with the crime. The letter had survived Emily’s discovery, and its recovery turns their secret correspondence into evidence against the husband who had tried to conceal it.

The marriage therefore operates on two connected levels. It changes the legal framework of Emily’s estate, making the old will void, and it supplies the cover for Alfred and Evelyn’s plan to gain her fortune. But Emily is not merely the passive subject of a financial scheme: after finding the letter, she seeks her solicitor, keeps the evidence, and attempts to destroy the new will. Her efforts do not save her, yet they disrupt the conspirators’ timing and leave behind the evidence that ultimately exposes the marriage’s hidden purpose.
