The Last Time I Saw You Summary: The Full Plot Explained
Spoiler Warning: This section reveals the complete plot, including the ending.
Lily Michaels is found bludgeoned to death inside her Baltimore home. Her husband, Harrison, discovers the body and calls for help.
At the funeral, Kate English’s estranged prep school friend Blaire Barrington reappears after fifteen years. During the burial, Kate receives an anonymous text saying the killer enjoyed her sorrow and is coming for her next.
Detective Frank Anderson leads the investigation. Kate begins receiving nursery-rhyme threats. Three dead mice with gouged eyes appear in her sink alongside a twisted “Three Blind Mice” note.
A box of three dead parakeets painted black follows. A distorted voice chants “Pop Goes the Weasel” with the lyrics changed to “Dead is the doctor.”
Suspicion falls on several people close to Kate. Her husband Simon is struggling financially and spending time with a younger colleague named Sabrina Mitchell.
Gordon Barton, the family financial manager, keeps a secret room filled with candid photos of Kate. Kate’s father Harrison is also hiding a violent argument he had with Lily before her death.
Blaire frames Simon by planting Lily’s stolen diamond bracelet and a burner phone in his office. Simon is arrested for the murder and the stalking.
Kate later finds Blaire’s journal and learns that Blaire orchestrated the entire psychological campaign. When confronted, Blaire reveals she is Lily’s biological daughter and Kate’s half-sister.
Blaire blames Kate for a long-ago car accident that caused Blaire to miscarry and left her infertile. She knocks Kate unconscious and sets the house on fire.
At the last moment, Blaire pulls Kate out of the burning building. A new witness, Georgina Hathaway’s driver Randolph, comes forward.
Georgina confesses that Lily had summoned her to reveal the truth about the secret child fathered by Bishop Hathaway. In a jealous rage, Georgina pushed Lily, who hit her head.
Georgina then staged the scene as a robbery by smashing a window and hitting Lily again with a bookend. Simon is exonerated and reconciles with Kate.
Four years later, Blaire is living in a psychiatric facility, believing she is a Hollywood movie star. Kate visits her sister, choosing compassion despite everything.
