Desc: The Clue of the Scarab: Albert Normand, the son of a wealthy banker, has married against his father's wishes, and disinherited, he supports his wife and child by performing the duties of attendant at the Egyptian Museum. Margaret Noble, an adventuress and leader of a clever band of swindlers, plans to obtain possession of some valuable jewels on exhibition at the Egyptian Museum. She visits the museum with the intention of stealing the jewels, and while there she drops an odd scarab brooch which is returned to her by the attendant. Her accomplice feigns a sudden illness, and in the excitement which follows, she succeeds in hiding in a mummy case. During the night she comes out of her hiding place, steals the jewels, and with the aid of her accomplices succeeds in getting away, but not before they have killed the night watchman of the museum, who tried to stop them. The authorities offer a large reward for the capture of the criminals, and searching for evidence, Albert finds a scarab brooch, which he recognizes as the one he returned to the woman the day before. He decides to try and trace the thieves. By chance, one day he meets a woman whom he recognizes as the one who dropped the brooch. He follows her to a gambling house, where she loses heavily, and anxious to make her acquaintance he loans her some money. This changes her luck and she invites Albert to her home, but she recognizes him as the attendant of the Museum, and afraid that he might order their arrest she succeeds in trapping him. Meanwhile Albert's coat has been found on the bank of a river, and his wife has asked his father for help. He advises her that he will give her child a home, but will not allow her to enter his house. The child goes to live with her grandfather, but every night she meets her mother at the gates. Margaret has lost all her money at the gaming tables, and hard up for cash, she calls on Roy Arden, the banker's secretary, who is madly in love with her, to help her in securing the money from the banker's safe. The banker, meanwhile, has changed the combination to his safe, and when the thieves find they cannot open it, they threaten him with murder. Little Mary is just returning from her nocturnal meeting with her mother when she hears the tumult in the banker's room, and learning the cause, she telephones for the police. They come just in time, as the old man would not have been able to hold out much longer. Little Mary can now have anything she desires as reward for her faithful services. She pleads for her mother, and the banker decides to visit his daughter-in-law. On arriving at the house they find husband and wife in each other's arms, as Albert has succeeded in escaping, and the family is happily reunited.
