A former college friend of his, Gavin Elster, hires Scottie to spy on his wife Madeleine, telling him that she has been acting strangely and he suspects she may be suicidal. Scottie trails Judy to an [[museum|art museum]], where he watches her for three hours as she stares intently at a portrait of Carlotta Valdes, a Spanish matron who has been dead for more than two centuries. Then she goes and buys flowers and puts them on Carlotta's grave. | A former college friend of his, Gavin Elster, hires Scottie to spy on his wife Madeleine, telling him that she has been acting strangely and he suspects she may be suicidal.
