Archdale moves through the Fairfield orbit as an old soldier with a knowing manner, the kind of man who holds a stirrup and lets drop a pointed word about who will inherit the old house and land. His casual talk about the estate and the people around it carries an unsettling edge, as though he is testing loyalties he already understands. He matters because his presence keeps the question of succession alive and uneasy, nudging the reader to watch every Fairfield claim with suspicion.
