The Fatal Ring (1917)

Episode 1: "The Violet Diamond" Pearl Standish, bored with society and longing for excitement, is held up by a masked man who demands the violet diamond of The Daroon. He tells her that her father bought the diamond from a villainous priest in Arabia who stole it from its rightful owner. The masked man, Nicholas Knox, has been given three days to recover the diamond or die at the hands of the Secret Order at the head of which is a priestess who stops at nothing to gain her end. The only man that might know something about this diamond is Richard Carslake, her father's former secretary. In spite of the knowledge that her father and he had a disagreement, she requests him to give her what information he has concerning the violet diamond. Just then Knox enters, Pearl points to him and says, "There is the man who has the gold setting in which the stone belongs." Immediately Carslake moves toward the door. Locking it and drawing his revolver, he demands the setting for the diamond. Searching Knox he finds the setting and is about to escape when through the window comes the priestess, accompanied by two of her spies, who sneak behind Carslake and knock the revolver from his hand. In the struggle which follows, Knox recovers the setting. After a struggle Carslake escapes and Pearl finds herself alone with Knox. Wishing to know the identity of the mysterious woman who helped him, Pearl asks Knox. "I can tell you nothing," is his reply. "Well then if you can tell me nothing, I want you to hand over that apparently much-valued setting for the violet diamond," Pearl assures, covering him. Assisted by her butler, Pearl secures this setting, but the spies come to Knox's assistance again and Pearl is attacked by an Arab. In a struggle with him on the stairs, she is hurled over the rail but catches on to the chandelier and falls to the floor. Knox is finally overpowered by the butler. Standing by a window, Pearl discovers a knife stuck in the wall. Pearl pulls this knife from the wall and discovers a note on it. "Fifteen days are allotted to you to return the violet diamond or die," it reads. "What is this mysterious diamond, the possession of which means such dangers?" is the question which will bring audiences back for the next chapter.
