It walked the whole length of the ample hall we have alluded to, and then, at the window from which had streamed the long flood of many coloured light, it paused.

For more than ten minutes this mysterious looking figure there stood.

At length there passed something on the outside of the window, that looked like the shadow of a human form.

Then the tall, mysterious, apparition-looking man turned, and sought a side entrance to the hall.

Then he paused, and, in about a minute, he was joined by another who must have been he who had so recently passed the stained glass window on the outer side.

There was a friendly salutation between these two beings, and they walked to the centre of the hall, where they remained for some time in animated conversation.

From the gestures they used, it was evident that the subject of their discourse was one of deep and absorbing interest to both.  It was one, too, upon which, after a time, they seemed a little to differ, and more than once they each assumed attitudes of mutual defiance.

This continued until the sun had so completely sunk, that twilight was beginning sensibly to wane, and then gradually the two men appeared to have come to a better understanding, and whatever might be the subject of their discourse, there was some positive result evidently arrived at now.

They spoke in lower tones.  They used less animated gestures than before; and, after a time, they both walked slowly down the hull towards the dark spot from whence the first tall figure had so mysteriously emerged.

There it a dungeon—­damp and full of the most unwholesome exhalations—­deep under ground it seems, and, in its excavations, it would appear as if some small land springs had been liberated, for the earthen floor was one continued extent of moisture.

From the roof, too, came perpetually the dripping of water, which fell with sullen, startling splashes in the pool below.

At one end, and near to the roof,—­so near that to reach it, without the most efficient means from the inside, was a matter of positive impossibility—­is a small iron grating, and not much larger than might be entirely obscured by any human face that might be close to it from the outside of the dungeon.

That dreadful abode is tenanted.  In one corner, on a heap of straw, which appears freshly to have been cast into the place, lies a hopeless prisoner.

It is no great stretch of fancy to suppose, that it is from his lips came the sound of terror and of woe that had disturbed the repose of that lonely spot.

The prisoner is lying on his back; a rude bandage round his head, on which were numerous spots of blood, would seem to indicate that he had suffered personal injury in some recent struggle.  His eyes were open.  They were fixed desparingly, perhaps unconsciously, upon that small grating which looked into the upper world.
