Gaspard had shut and locked the trap-door above.

Oliver sat dazed and bewildered by the suddenness of what had happened. Presently he turned his head mechanically and looked around, and his eyes fell upon the silent occupant of the bed.

Then he leaped to his feet, and up the steep flight of stone steps like a madman. He dashed his fist against the cold iron lid above his head. "Open," he shouted—"open and let me out. Let me out and you shall have everything. Here are the bottles of water. Do you not want them?"

He stopped short and listened, crouching upon the upper step, close against the iron lid above him. He fancied he heard a faint sound of footsteps.

"Let me out!" he screamed again.

Nothing but dead, solemn silence.

Oliver ran down the steps again, the accursed glass bottles clicking together in his pocket. In the narrow vestibule below he stood for a moment, gazing down upon the floor in the utter abandonment of blank despair. At last he looked up, and then crawled fearfully forward into the room beyond, lit by the faint glow of the lantern. He sat him down upon the floor, and burst out crying. By-and-by a blind rage filled his heart against the cruelty of his fate and against the man who had brought it all upon him. He sprang to his feet, and began striding up and down the room, muttering to himself and shaking his head. Presently he stopped, raised his clinched fists in the air and shook them. Then he broke into a laugh. "Very well," said he; "but you have not got the bottles of water!" and he felt his pockets; they were still there.

Then, as he stood there feeling the bottles in his pocket, the last misfortune of all happened to him. There was a flare, a sputter, and then—utter darkness.

The light in the lantern had gone out.
