Caroline couldn't follow through with the mail order marriage she had agreed to, so she switched places with the woman next to her on the train. Anxious to get home, she had more reason to hurry when she received a wire relaying a family emergency.Traveling with the Union Pacific across the mid- west was a long, hot trip and Caroline's temper flared at the man who took responsibility for the railroad.
