Le Fever’s son is the son of Lieutenant Le Fever and is Toby’s unofficial adopted son. A deeply loyal and sensitive boy, Le Fever’s son dedicates himself to caring for his dying father in the local inn despite having no one else in the world. To Trim’s great frustration, other guests in the inn, like the curate, fail to comfort the boy. After Le Fever’s death Toby takes Le Fever’s son in, giving him a basic education before sending him to a boarding school. Le Fever’s son visits Toby during holiday and eventually asks for his blessing to go to Hungary to fight the Turks, but his military escapades are largely unsuccessful. Le Fever’s son returns to England shortly after Tristram’s birth, prompting Toby to recommend him to Walter as an ideal governor for Tristram.
