The Heart of a Cracksman (1913)

Carlton, disapproving of his dissipated son and the latter's scheming wife, on his death-bed makes his will in favor of his devoted niece, Marcia. Hearing of this the previous couple plan to balk the father; their scheming is overheard by the cracksman, who has stealthily entered the house. The son and his wife retire and the cracksman creeps upstairs and enters Marcia's room. Affected by her beauty and innocence as she lays sleeping, he determines to assist her; following the son into the sick man's room he snatches the stolen will from his hand.
