Her suicide story was an act. Tom realizes he has been tricked, but the guests have heard his confession and say they will testify to it. THE CONFESSION IS REAL Sally invented the poisoning to expose the real killing. Gregory is cleared in the eyes of the party; Tom is exposed. 16 / STORY BEAT 17 66:00–67:58 She explains how the clues fit The button came from the living-room couch: Sally saw where it had been freshly pulled off. It placed Misha there when he died. Tom’s “couch” slip showed he knew that location, leading her to identify him as the killer. But a button and a verbal slip seemed too weak against Gregory’s public confession, so she made Tom confess too. OBSERVATION BECOMES EVIDENCE The clues gave Sally a suspect. Her deception produced a confession heard by others. She credits her mystery writing. ↪ Connects to beat 12 17 / STORY BEAT 18 68:08–68:40 Gregory accepts Sally’s writing Gregory recognizes that Sally’s detective skills have saved him from being blamed for murder.
