Fear had likely driven Sheldon Yale, after murdering his brother, to lay hands on his own biological father—precisely because of an early leak of this Will to his ears.
At that time, seizing the opportunity when Chester Yale was estranged and outcast, Sheldon forged a fake Will to inherit everything from the Yale Family, and, fearing the exposure of his deeds, he crazily cast out those who knew the truth back then and silenced them.
So many years had passed and Sheldon probably thought that no one would ever discover his conspiracy.
But what he never expected was that retribution is inescapable, and, as fate would have it, the sudden death of his son in a car accident left him without an heir, forcing him to retrieve Chester Yale at any cost and raise him as his own successor.
Sheldon must have believed that Chester would never be able to learn the truth and would foolishly remain in the dark, working on his behalf.
