follows Madeleine to a florist, where she buys a bouquet, to the Mission San Francisco de Asís and the grave of Carlotta Valdes (1831–1857), and to the Legion of Honor art museum, where she gazes at the Portrait of Carlotta. He watches her enter the McKittrick Hotel, but upon investigation, she does not seem to be there. A local historian explains that Carlotta Valdes committed suicide: she had been the mistress of a wealthy married man and borne his child; the otherwise childless man kept the child and cast Carlotta aside. Gavin reveals that Carlotta (who he fears is possessing Madeleine) is Madeleine's great-grandmother, although Madeleine has no knowledge of this and does not remember the places she has visited. Scottie tails Madeleine to Fort Point and when she leaps into the bay, he rescues her.

Judy drafts a letter to Scottie explaining her involvement: Gavin deliberately took advantage of Scottie's acrophobia to substitute his wife's freshly killed body in the apparent "suicide jump." However, Judy rips up the letter and continues the charade because she loves Scottie. They begin seeing each other, but Scottie remains obsessed with "Madeleine." He asks Judy
