The bookstore closes for summer holidays, and Don and Prudence leave on a bus tour, where Prudence grows closer to Don as she understands his passion to become an architect. They continue on by themselves to Lago Maggiore for a tour of the garden spots of northern Italy, the Italian Alps with "Al Di Là" playing over the chairlift speakers, and Verona with its Romeo and Juliet balcony. At the market place, Prudence coincidentally runs into Albert and his mother, and is concerned that this woman will report to her mother back in the U.S. that she is no longer on the bus tour, but on a romantic trip with Don. Prudence quickly excuses herself, telling Albert and his mother that she must leave, and fleeing with Don out of the market then and on a night train to Rome.
