She tried to get out the revolver with her left hand; but, before she could do so, Sophie and Fargeau had opened fire, and at Sophie's first shot, she clasped her hand to her side, and went down beside Hardress. Lord Orrel had a bit of his left ear snipped off, and the president got a flesh wound just below the left shoulder. The two admirals, who had already taken their seats in the car, with Madame de Bourbon and the Russian professor, sprang to their feet; but, before they could leave the car, a strange and awful thing happened. A blinding glare of light shone out from the southern tower, where Doctor Lamson had been watching the departure through his night-glasses. The thin ray wavered about until it fell on Sophie Valdemar and Adelaide de Condé, still standing close together, with Victor Fargeau just in front of them. For a moment their faces showed white and ghastly in the blazing radiance; and then, to the amazement and horror of those who saw the strangest sight that human eye had ever gazed upon, down the ray of light, invisible, but all-destroying, flowed the terrible energy of the disintegrator on the top of the tower. Their hair crinkled up and disappeared, the flesh melted from their faces and hands. For an instant, two of the most beautiful countenances in Europe were transformed into living skulls, which grinned out in unspeakable hideousness. Then their clothing shrivelled up into tinder, and all three dropped together in an indistinguishable heap of crumbling bones. CHAPTER XXX Almost at the moment that the man and the two women who, but a few moments ago, had been standing in the full pride of their youth and health and beauty, had dropped to the earth in little heaps of crumbling bones, whistles sounded inside the works, and a number of men came out of the western gate, some of them armed with rifles and revolvers, and others carrying stretchers. Hardress and Chrysie were lifted on to two of these, and Lady Olive went back into the works with them. Lord Orrel and the president, after having their wounds hastily bandaged for the time being, went to the door of the saloon carriage, and Lord Orrel said, shortly and sternly: "Madame de Bourbon, as you have seen, your niece has ceased to exist. Count Valdemar, the same is true of your daughter. And as for you, gentlemen," he went on, turning to the two admirals, "you have seen something of those means of defence of which I spoke to you after dinner.
