One day early in this two-week vacation, Mark climbs the hill overlooking the surrounding area and finds a 21-year-old girl named Julie Danvers with blue eyes, dandelion-colored hair, and wearing a white dress. She tells him that she is from the year 2201 and that she is able to come back due to her father inventing a time machine. Mark does not believe her, but goes along with her imaginative tale. After talking for a few hours, Julie leaves, telling him that she will be back the following day at the same time. Mark returns the next day to find her there, this time wearing a blue dress. They talk for several hours again and get to know more about each other. Julie tells more about her father, whom she thinks very highly of, and the fact that he is an invalid that she must take care of. Despite breaking laws set by the time police to come back in time, Julie still manages via her father's personal time machine. She also states the Novikov self-consistency principle, two decades before he formulated it. Mark and Julie part once more with plans to meet up again. Mark has quickly fallen in love with Julie, but hates himself due to his marital situation and the fact that he has never even so much as looked at another woman since he married Anne.
