Part 1 opens with Jem Haworth, who rose from collapsing in a snowy field two decades ago to owning the successful Haworth Iron Works in Lancashire, reflecting on his harsh labor and how it shaped his resilient character, while interwoven vignettes of his inventor father’s struggles and working-class family life contrast sharply with his current success. This early background provides insight into social mobility and sacrifice, revealing that honesty and diligence underpin Jem’s identity, and the budding relationships with the inventor’s son Murdoch and the laborer’s daughter Janey Briarley suggest the emotional core of the novel.
