Who is the man in the yellow suit

The man in the yellow suit is the main antagonist of the novel. After witnessing the Tucks “kidnapping” Winnie, the man starts formulating his evil plots to gain land and money. Later in the novel, the man steals the Tucks’ horse and returns to the Fosters’ home, where he makes Winnie’s parents give up their land in exchange for Winnie’s safety. Since the spring is on the Fosters’ land, he now possesses the spring, and plans to sell the water to the public in addition to forcing Winnie to drink some. In response, Mae Tuck kills him by hitting him over the head with a shotgun.
