Key passages

  • I think I’m justified in telling you this. Mr. Carleton didn’t love Madeleine, and he did love another girl. Madeleine worshipped him, and I think he came last night to ask her to release him, and she refused, and then⁠—and then⁠—

    Mrs. Markham suggests that Carleton came to break off the engagement, and when Madeleine refused, he may have killed her.

    This theory introduces a possible motive for Carleton, challenging Fessenden's belief in his friend's innocence.

  • The will she burnt was a later one, that didn’t give her this house. She burnt it so the earlier one would stand.

    Kitty French theorizes that Miss Morton destroyed a newer will that did not benefit her, leaving the older will that bequeathed the house to her as the valid one.

    This deduction points to Miss Morton's potential motive for murder and cover-up.
