The Face in the Dark (1918)

Jane Ridgeway, the daughter of retired Secret Service man Charles Ridgeway, has inherited her father's knack for solving crimes and puts her talent to work when her sweetheart, Richard Grant, is accused of robbing a bank. Her father, now a bank examiner, works in collusion with two thieves who are acquainted with a master criminal known only as "the Face in the Dark." When the evidence implicates her father in the robbery, Jane confronts him, and although Richard is released from jail, Ridgeway escapes. The two crooks lead him to the Face in the Dark, but as the two men are shaking hands, the place is raided by Secret Service agents who arrest the mysterious criminal and congratulate Ridgeway for his fine detective work. Jane is happily reunited with her sweetheart and her father.
