"'Capital idea, Frantz. Dr. Weber pretends that I drink too much Burgundy; we must counteract that with mineral water. This little lake looks inviting.' "Then he fastened the pony to the trunk of a tree, and waved his hand in adieu. Sitting down on the moss, he commenced to take off his boots, and, as I walked away, he called after me:-- "'In an hour, Frantz.' "They were his last words. "An hour after I returned. The pony, the carriage, and Sir Thomas's clothes were all that I could see. The sun was going down and the shadows were lengthening. Not a sound of bird or of insect, and a silence as of death filled the solitude. This silence frightened me. I climbed on to the rock above the cavern, and looked right and left. There was nobody to be seen. I called; no one responded. The sound of my voice repeated by the echoes filled me with terror. Night was coming on. All of a sudden I remembered the disappearance of Loisa Muller, and I hurried down to the front of the cavern. There I stopped in affright, and glancing towards the entrance, I saw two red, motionless points. [Illustration: "I SAW TWO RED, MOTIONLESS POINTS."] "A second later I distinguished some dark moving object farther back in the cavern, farther perhaps than human eye had ever before penetrated; for fear had sharpened my sight, and given all my senses an acuteness of perception which I had never before experienced. "During the next minute I distinctly heard the chirp, chirp of a grasshopper, and the bark of a dog in the distant village. Then my heart, which had been frozen with terror, commenced to beat furiously, and I heard nothing more. With a wild cry I fled, leaving pony and carriage. "In less than twenty minutes, bounding over rocks and shrubs, I reached my cousin's door. "'Run, run,' I cried, in a choking tone, as I burst into the room where Dr. Weber and some invited friends were waiting for us. 'Run, run; Sir Thomas is dead; Sir Thomas is in the cavern,' and I fell fainting on the floor. "All the village turned out to search for the commodore. At ten o'clock they returned, bringing back Sir Thomas's clothes, the pony, and carriage. They had found nothing, seen nothing, and it was impossible to go ten paces into the cavern. "During their absence Agatha and I remained in the chimney-corner, I still trembling with fear, she, with wide open eyes, going from time to time to the window, from which we could see the torches passing to and fro on the mountain, and hear the searchers shout to one another in the still night air. "At her master's approach Agatha began to tremble. The doctor entered brusquely, pale, with set lips. He was followed by about twenty woodcutters, shaking out the last remnants of their nearly extinguished torches. "He had barely entered before, with flashing eyes, he glanced round the room, as if in search of something. His eyes fell on the negress, and without a word being exchanged between them the poor woman began to cry.
