Olivia decides the memoir is actually a structured treasure hunt set by Vincent, with each story as a clue. She dismisses the idea that his dementia symptoms are staged, noting Alma’s intolerance for games and Vincent’s genuine panic during night terrors and confusion when he mistakes Olivia for her mother. Olivia concludes Vincent either wants to confess or wants her to solve the murders, but, as in her childhood, he expects her to find the truth herself.

At their next session, Olivia immediately tells Vincent she has been to the old house on Van Buren, which he still owns. She asks why he did not disclose that earlier and requests permission to go there to write instead of breaking in again. Vincent calls her detective work inappropriate but is intrigued when she admits she entered through the back door window, a trick he and Danny used as kids.

Olivia presses him on why he kept the house. Vincent recounts that after the murders the family had to remain there because they could not afford to move and no one would buy it. After he moved out, his parents eventually rented it; his father died in 1978 and his mother in 1980. A long-term tenant, Frieda, stayed for years, making it practical to retain the property. He grants Olivia unrestricted access and suggests she claim to be the new tenant if questioned.

Olivia privately contemplates her debts and the possibility of living there herself, then returns to the investigative thread. She tells Vincent she found Poppy’s hiding nook in the window, validating that his earlier “hallucination” referenced a real space. Vincent deflects, saying he and Poppy knew each other’s secrets.

Choosing to push further, Olivia shows Vincent a photograph from inside Poppy’s closet: the message “Someday soon, you’ll be dead,” which appears to be written in Vincent’s handwriting. She expects fear or alarm, but Vincent laughs, an unsettling reaction that complicates her sense of his intentions and what the message signifies.
