Mr. Gryce testifies about the broken hatpin found in the register, which matches the one removed from the victim's head, establishing the murder weapon. ## Themes in this chapter ### Deception and Appearance The murder weapon—a hatpin taken from the victim's own hat—highlights the deceptive and intimate nature of the crime. ### Marriage and Romantic Relationships Miss Ferguson's testimony reveals the strained marriage between Howard and Louise Van Burnam, marked by arguments and mistrust. ### Observation and Deduction Amelia Butterworth's careful observations of the couple entering the house and Mr. Gryce's detective work in finding the hatpin demonstrate the theme of deduction. ## Character check-ins ### Amelia Butterworth Called as a witness at the inquest; describes the couple she saw entering the Van Burnam house and expresses doubt about identifying the man. ### Mr. Gryce Testifies about the discovery of the broken hatpin in the register, linking it to the murder weapon. ### Miss Ferguson Testifies that Howard and Louise Van Burnam boarded with her in Haddam and describes their quarrel before Louise left for New York. ### Howard Van Burnam Mentioned in Miss Ferguson's testimony as the husband who argued with Louise about her trip to New York. ### Louise Van Burnam Mentioned in Miss Ferguson's testimony as the wife who insisted on going to New York against her husband's wishes. ### Coroner Dahl Presides over the inquest and questions witnesses, including Miss Ferguson and Amelia Butterworth. ## Key lines > The end found in the register and the end which the Coroner's physician had drawn from the poor woman's head were both handed to the jury, and it was interesting to note how each man made his little effort to fit the two ends together, and the looks they interchanged as they found themselves successful. The two pieces of the hatpin—one from the register and one from the victim's head—were given to the jury, who tried to fit them together and exchanged knowing glances when they succeeded. _Amelia observes the jury's reaction to the matching hatpin pieces._ > It was like a stream of limpid water flowing from a most unsightly-looking rock. Her voice was beautiful and clear, contrasting sharply with her plain appearance. _Amelia's metaphor describing Miss Ferguson's voice._ > I have thought I could do so if I saw him under the same circumstances as those in which my first impression was made. But lately I have begun to doubt even that. I should never dare trust to my memory in this regard. I believed I could identify him only under the exact conditions I first saw him, but now I am uncertain and would not rely on my memory. _Amelia expresses doubt about identifying the man she saw._ ## Links - HTML: https://www.betterreads.online/discover/that_affair_next_door_se/chapters/x-important-evidence - Book: https://www.betterreads.online/discover/that_affair_next_door_se - All chapters: https://www.betterreads.online/discover/that_affair_next_door_se/chapters
