The narrative follows Paul Palmer, a hardworking sixteen-year-old who sells magazines on the train to support his mother and younger sister. Encounters with a benevolent passenger lead to patronage and connections with an artist and a family circle that bring both opportunities and misunderstandings. Paul endures danger, false accusation, and a railway catastrophe that prompt a change of work, advancement in an office, and later involvement in mining and business dealings. His steady industry, quick thinking, and integrity lead to promotions, the foiling of criminal schemes, revelations about others, and the resolution of romantic and social entanglements.
