last night. Margery's friend Marcia Keane and a family cousin Roley Vavasour have been staying at the house since the voices started. Lady Stranleigh writes to thank Margery for the chocolates she sent and tells her that she has been laid low by food poisoning. Margery tells Satterthwaite she did not send her mother chocolates, but neither she nor her mother make the connection that Satterthwaite does, that the mysterious chocolates are the source of the food poisoning. Roley organizes a séance, with the spiritualist Mrs Casson and the medium Mrs Lloyd. After speaking to the medium's spirit guide, the voice of Lady Stranleigh's sister Beatrice comes through. Satterthwaite tries her with a question from long ago that only she will know, and she answers correctly. The spirit of Beatrice says "Give back what is not yours." Roley is the next heir to the title and estates should Lady Stranleigh die. He has asked Margery to marry him but she has refused, being engaged to the local curate. Lady Stranleigh wires that she is arriving home early, so Satterthwaite returns to London. Once there, he learns that Lady Stranleigh was found dead in her bath at Abbot's Mede.

Alice Clayton, her full name, reminds Satterthwaite she is the same maid who, many years earlier, he had kissed in a hotel's passage. He remembers Alice had brown eyes. He tells Margery that the woman she knows as Clayton, with blue eyes, is her Aunt Beatrice. She has a scar where she was struck on the head during the sinking of the Uralia and he imagines this blow destroyed her memory at the time. Her avaricious sister used the opportunity to say her elder sister drowned so she might inherit the family money. It is only now that Beatrice's memory is returning, thus persecuting her niece, and then killing her younger sister. The two go to Clayton's room but find the woman dead from heart failure. As Satterthwaite says,
