That Affair Next Door · Chapter

Miss Butterworth’s Theory explained

Amelia Butterworth develops a theory that the murdered woman is not Louise Van Burnam but rather a rival, and that Louise herself is the murderer.

What happens

Amelia Butterworth develops a theory that the murdered woman is not Louise Van Burnam but rather a rival, and that Louise herself is the murderer. She reconstructs the events of the night, including the use of a hatpin as the weapon and the woman's escape after pulling down the cabinet. She acknowledges the evidence of the scar and rings but argues they could be explained away, and concludes that Howard Van Burnam perjured himself to protect his wife.

Themes in this chapter

  • Jealousy and Revenge

    Amelia's theory centers on Louise Van Burnam's jealousy of a rival, leading to a murder driven by revenge.

  • Deception and Appearance

    Howard Van Burnam's false identification and the women's disguises highlight the theme of deception and the gap between appearance and reality.

  • Observation and Deduction

    Amelia uses careful observation of details (hats, gloves, pins, scars) to construct her deductive theory.

    Shows Amelia's intense mental focus on the case.

  • Which of the two had perished? We had been led to think, and Mr. Van Burnam had himself acknowledged, that it was his wife; but his wife had been dressed quite differently from the murdered woman, and was, as I soon began to see, much more likely to have been the assassin than the victim.

    Amelia questions whether the dead woman is really Louise Van Burnam, noting the difference in dress and suggesting Louise could be the killer.

    Core of Amelia's theory.

  • But that she, a woman, and not Howard, a man, drove this woman’s weapon into the stranger’s spine, I will yet prove, or lose all faith in my own intuitions.

    Amelia is determined to prove that a woman—Louise—used the hatpin to kill the victim, not Howard.
