Heath, quickly realizing what is in store for him, deserts Aimee and takes the next train out of town. Judge Bartlett Richmond, who was to marry the couple, consoles Aimee. Meanwhile, Kate, who is on her way to the expected wedding, meets Heath on the train. Not knowing who he is, Kate quickly falls in love with him.When Kate learns that Heath is her cousins fianc, she pretends that she had only been flirting because she thinks that falling in love with a man who is about to marry someone else is not appropriate. She vows to act in the proper way, the way in which the characters in her modern novels would. She does her best to bring Heath and Aimee back together again, even though she still loves Heath. ........
