The Perfidy of Mary (1913)

Rose and her cousin Mary dwell in the land of romance, but real Romeos are scarce in this prosaic age. Yet Rose, in spite of a gay young Lothario who steps in the way of her own true love, finds her way to love-land. That was where Mary's perfidy came in. It showed up Lothario's true character, while at the same time it brought Mary back to her own determined young lover.
