Being the eighth story of "What Happened to Mary." In this picture we see Mary as a public stenographer. Mr. Foster, a lawyer, has her write a letter to Abraham Darrow, stating that a new will is ready for his signature, but that the son, Terence Darrow, prevents the lawyer's access to the old man's bedside. Mary immediately volunteers her assistance in getting into the house and having the will signed. Terence Darrow sees Foster and Mary coming out of the office building and follows Mary to his home in time to prevent her entering. He then goes in, sits down, lights a cigarette and sends the old housekeeper out for some whiskey. Falling asleep, his cigarette drops from his fingers and sets fire to the rug. Mary, in the meantime, goes into the alley and slips in the back way when the old housekeeper comes out. She is detected by Terence attempting to steal through the room and a terrific struggle ensues, but Mary escapes to the yard again and gets the bottle of whiskey and a shawl from the old housekeeper by a trick and reenters, this time being successful in escaping detection. She locks Terence in the room, reaches the old man and gels the will signed just as Terence breaks into the room. The fire caused by the cigarette has meanwhile gained such headway that the firemen have their ladders up and one of them reaches the window just in time to knock Terence down as he attempts to wrest the will from Mary. The fireman then picks Mary up and starts down the ladder, but is followed by Terence and a desperate fight takes place on the ladder. Terence in an endeavor to kick the fireman off loses his balance and falls to the ground. The fireman brings Mary safely down. She quickly recovers consciousness and lakes the signed will to Mr. Foster.
