The descent of the water came upon him at last as a surprise. He was swimming round and round, and had not for some time touched the wall, when suddenly a ray of light flashed in his face. He gave a cry of joy. The water had fallen below the top of the loophole, and swimming up to it, he could see across the fosse, and watch the sunlight sparkling on the water. It was two months since he had seen the light, and the feeling of joy overpowered him more than the danger he had faced.
Rapidly the water fell, until it was level with the bottom of the loophole. Then hours passed away; for the fosse would have to be emptied before the drain leading from the dungeon could be opened. However, Rupert hardly felt the time long. With his hands on the bar and in the loophole, he remained gazing out at the sunlight.
The water in the fosse sank and sank, until he could no longer see it; but he could see the sun glistening on the wet grass of the bank, and he was satisfied. At last he was conscious of a strain on his arm, and withdrawing his gaze from without, he saw that the water had fallen six inches.
It now sank rapidly; and in an hour he could stand with his head above it. Then he was able to sit down on his bed; but when the water sank to a depth of two feet, he again lay on his back and floated. He knew that a thick deposit of mud would be left, and that it was essential for his plan that he should drift to the exit hole of the water, and there be found, with the mud and slime undisturbed by footsteps or movement. Another ten minutes, and he lay on his back on the ground in a corner of the dungeon to which the water had floated him, having taken care towards the end to sink his head so that his hair floated partly over it, and as the water drained off remained so. He guessed it to be about midday, and he expected to be left undisturbed until night.
After a time he slept, and when he awoke it was dark, and soon after he heard steps coming down the stairs. Now was the moment of trial. Presently the door opened and four of the gaolers came in. They bore between them a stretcher.
"This is the fifth," one said, and he recognized the voice of his own attendant. "It is a pity, he was a fine fellow. Well, there's one more, and then the job's done."
He bent over Rupert, who ceased breathing.
"He's the only one with his eyes closed," he said. "I expect there's someone would break her heart if she knew he was lying here. Well, lift him up, mates."
The two months' imprisonment in the dungeon had done one good service for Rupert. The absence of light had blanched his face, and even had he been dead he could hardly have looked more white than he did. The long hours in the water had made his hands deadly cold, and the hair matted on his face added to the deathlike aspect.
"Put the stretcher on the ground, and roll him over on to it," one of the men said. "I don't mind a dead man, but these are so clammy and slimy that they are horrible to touch. There, stand between him and the wall, put a foot under him, roll him over. There, nothing could be better! Now then, off we go with him. The weight's more than twice as much as the others."
