"I can well believe it," Brodie assented calmly. "One moment, if you please." He held the stone in the palm of his hand and fitted a magnifying glass into his eye. There was a moment's silence. Henriette suddenly gripped her companion's hand. Mademoiselle Larilly stood there, panting, her bosom rising and falling quickly. There was murder in her eyes. Presently Brodie let the stone fall, replaced the magnifying glass in his pocket. He stood, for a moment, as though thinking. Then he turned towards the door. "Miss Larilly," he said, looking back at her, "my apologies. The bauble which you are wearing is a worthless piece of yellow crystal, worth, perhaps, twenty pounds. I was deceived--as was, perhaps, the young lady over yonder," he added with a little ironical bow--"by a wonderful resemblance." He closed the door quietly behind him. There was a queer silence in the room. Henriette was deathly pale. Relief and bewilderment were struggling in her face. The French girl's expression had become electrically transformed. With a sudden little gesture she leaned towards the closed door. Her hand flashed in front of her face. Her gesture was significant if vulgar. "It is worth twenty pounds, my bauble, is it?" she mocked. "And he thinks, that big, ugly man, that I would come on to the stage with a bauble round my neck worth twenty pounds! Eh, but he is not a gentleman of France, that----!" An inner door suddenly opened. Leopold Brinnen appeared, and behind him the tall, slender figure of Monsieur Larkson, the leading French actor in the revue. "With your permission," Brinnen began, bowing to Mademoiselle Larilly.... "Henriette!" He stopped short in amazement. Henriette rose to her feet and came towards him. "Leopold," she exclaimed, talking to him rapidly in French, "what have you done? How dare you, for all our sakes, run these awful risks! If the man Brodie had not been a fool, if he had known anything of jewels, if he had not been blind, where should we have been at this moment? Do you think they would have let mademoiselle go until she had told from whence came the Yellow Eye? Oh, but you are so reckless! Take it away from her quickly! Hide it!" Leopold listened to her words a little gravely. "Will you tell me, my sister," he enquired, "what you are doing here?" "I have dined and am spending the evening with Mr. Aaron Rodd," she explained. "We sit in the box here and I recognise the Yellow Eye. I hurry here. Mademoiselle receives me. I beg her to take it off, not to wear it. I warn her that there is danger. She scoffs at me. And then Brodie comes. But that man--he must be mad! He held the stone in his hand." The young man smiled quietly. Then he listened at the door which led into the passage and softly turned the key. He glanced towards mademoiselle. "Ah, but if you all will," she exclaimed, "behold!"
