The little chocolate cake was not on the dinner menu, and the candle was not supposed to be there. Nora Ellis knew both facts as she carried the white dessert plate through the narrow aisle of the Summit Star's dining car.

Outside the broad windows, snow still clung to the mountain peaks, although the valleys below were turning the colors of autumn. Inside, the brass lamps glowed against polished walnut panels, and an elderly man in a brown tweed jacket was trying very hard not to let his wife see that his hands were trembling.
Nora had served hundreds of passengers during her three years on the train, but she had never seen anyone look at a single unlit candle as if it could save something precious.
It was the fiftieth wedding anniversary of Walter and Evelyn Mercer. They had not ordered a celebration, and they had certainly not paid for one. The reservation merely listed two standard dinners and a third seat for Evelyn's older sister, Margaret Lowell.
Nora had learned about the anniversary only because Margaret had approached the service counter that afternoon and asked, with the embarrassed politeness of a person accustomed to going without, whether a candle might be possible. "Nothing elaborate," she had whispered. "Evelyn used to love birthdays and anniversaries. Walter says she sometimes forgets the date now, but she still remembers a flame on a cake."
Nora had glanced at the dessert refrigerator and seen one small square of chocolate cake left from the afternoon service. Its edges were slightly crooked, and it was too modest for the expensive dining car's printed dessert list.
She had also seen the supervisor's notice taped above the counter: NO COMPLIMENTARY FOOD WITHOUT AUTHORIZATION. The railway was reviewing every expense. Staff who ignored the new rules would lose shifts, and Nora could not afford to lose even one. She had stood there for a long moment before taking three dollars from her tip envelope, putting it in the register, and asking the cook if he could spare a candle from the crew's birthday tin.
Now the cake was balanced in her hands, its small flame steady despite the train's gentle movement. Walter sat with his back to the aisle, his shoulders stooped inside a jacket that had clearly been cared for over many winters. Across from him, Evelyn wore a burgundy blouse and a little gold brooch shaped like a leaf. Her silver hair had been pinned carefully behind her ears, and her expression drifted between alert curiosity and a worried search for something she could not quite name. Margaret, seated beside her, wore black and watched her sister with the soft vigilance of someone who had learned when to help and when to wait. When Nora set the plate down, all three looked up.
