At the station where the aunt waited, Tommy searched his pockets for something to give them. He owned a pencil stub, the torn timetable, and the few coins Walter had insisted he keep. He borrowed the back of their unused honeymoon excursion ticket and wrote a sentence in large, determined letters: NO ONE RIDES ALONE IF I CAN HELP. He signed it TOMMY and handed it to Evelyn. "I can't pay you back," he said. Walter told him that the ticket already was payment enough. Evelyn hugged him and replied, "You don't have to pay us. Just remember what it felt like when somebody stayed."
The three of them parted there. Walter and Evelyn eventually reached their boardinghouse two days late, muddy, tired, and almost out of money. They laughed about it for years. They wrote to Tommy's aunt once, received a short reply saying he was safe, and then lost the address during a move. There had been no easy way to search for a boy with a common name across several states in those days, and later life filled their home with work, bills, illness, and other responsibilities. The faded ticket remained tucked in a drawer with their wedding photograph. Whenever they argued about money or felt exhausted by other people's demands, Evelyn sometimes took it out and reminded Walter what their first journey had taught them.
Now, fifty years later, Walter had brought the ticket onto the Summit Star in the pocket nearest his heart. He had planned to show it to Evelyn over dessert, hoping the familiar words might bring back the memory of the frightened boy. It was not a test. He had promised himself not to test her memory anymore, because every question with a right answer carried the possibility of hurting her. He wanted only to give her a piece of their shared story, the way a person might place a warm blanket around somebody already sitting comfortably. He did not expect the words on that ticket to be recognized by anyone else.
Thomas Avery stepped closer to the table and looked from Walter to Evelyn. "Forgive me," he said. His normally even voice sounded unsteady. "May I ask where you got that ticket?" Walter glanced down as though checking that it was still there. "It was given to us by a boy on this line a very long time ago." Thomas swallowed. "Did he sign it Tommy?" The question seemed to change the air in the carriage. Nora heard Margaret draw in a breath, and Walter's hand closed protectively over the old paper. "Yes," the elderly man answered. "Why do you ask?"
Thomas removed his cap. Beneath his silver hair, Nora could see the pale mark of a childhood scar above his left eyebrow, the kind of small detail no stranger would think important. He had never spoken much about his early life, not even at crew dinners when everyone else
