Vintage Season
 The story is set in an unnamed American city at about the time of publication. There are several mentions of how beautiful the weather is. Oliver Wilson is renting an old mansion to three vacationers for the month of May. He wants to get rid of them so he can sell the house to someone who has offered him three times its value, provided the buyer can move in during May. His fiancée, Sue, insists that he arrange for them to leave, so that he can sell the house, giving them enough money for their impending marriage. The tenants are a man, Omerie Sancisco, and two women, Klia and Kleph Sancisco. They fascinate Oliver with the perfection of their appearance and manners, their strange connoisseur's attitude to everything, and their secretiveness about their origin and about their insistence on that house at that time. Oliver's half-hearted attempts to evict them founder when he becomes attracted to Kleph. The mystery deepens with remarks she lets slip, with the unspectacular but advanced technology of things she has in her room—including a recorded "symphonia" that engages all the senses with imagery of historical disasters—and with the appearance of the would-be buyers, a couple from the same country, who plant a "subsonic" in the house intended to drive the residents out. Hearing Kleph sing "Come hider, love, to me" from the Prologue to Chaucer's Canterbury Tales, Oliver realizes that she and her friends are time travelers from the future. He traps Kleph into admitting they are visiting the most perfect seasons in history, such as a fall in the late 14th century in Canterbury. At the end of May, more time travelers visit the house. A meteorite lands nearby, destroying buildings and starting fires—the "spectacle" that the time travelers wanted to end their visit with. Oliver's house survives, as the visitors had already known it would. The time travelers leave for the coronation of Charlemagne in 800, except Cenbe, the genius who composed the symphonia Oliver had experienced. In conversation with Oliver, Cenbe admits that the time travelers could prevent the disasters they savor but do not do so because changing history would keep their culture from coming to be. Oliver goes to his room, feeling ill. In a short scene set in the future, the final version of Cenbe's symphonia is performed, including a powerful image of what is apparently Oliver's face in the "emotional crisis" induced by his conversation with Cenbe. Oliver writes down a warning about the time travelers, which he hopes will change history. However, he dies of a new plague, and the house and the unread message are destroyed in a futile effort at quarantine.
