In Gavin Elster's office, Scottie's rich former classmate explains his predicament.
Elster's wife Madeleine has been acting strange. She disappears for afternoons at a time, spaces out regularly, and seems to be possessed by a ghost.
At first, Gavin had blamed the change on San Francisco—"You know what San Francisco does to people who have never seen it before." Now he's not so sure.
Scottie scoffs at first and suggests that Elster take his wife to a psychiatrist, but curiosity gets the better of him and he agrees to look into Madeleine's strange case.
