A way of solving the difficulty presented itself. He suddenly turned the key in the lock, clicking it loudly, to the end that, if Ivar were really within, he could not fail to learn that he was now a prisoner.
Godfrey listened. There was no cry of surprise: no hasty rush of feet to the door: no movement at all. After waiting a few moments, he came to the conclusion that the room was untenanted.
He turned the key, and pushed open the door.
Aided by a subdued light, tender and dreamy, that stole through a latticed casement, he had visible proof that the chamber was devoid of anything in human shape. The cypress chest had also vanished.
No way of egress was visible save by the window; but Ivar had not made his exit by this, as the state of its fastenings clearly showed. His disappearance was obviously due to the existence of some secret passage.
Godfrey, loth to turn back now that he had come thus far, resolved to make an examination of the room, even at the risk of being discovered by the returning Ivar.
He began his search with the fireplace.
Surely some propitious fairy was directing his steps! A long slab of stone, that formed one side of the fireplace, had sunk to the level of the hearth, revealing a passage behind. This slab was worked by a pulley, since he could feel at each side the ropes by which it had been lowered; but without stopping to examine the mechanism, he entered the passage and moved forwards through the darkness, exploring the way before him both with hand and foot in order to guard against a possible precipitation down a flight of stairs. The sequel justified this precaution, for he soon found himself at the head of a flight of stone steps. He counted forty of them before he reached the level flooring of another passage. At the end of this a faint light could be seen proceeding from behind a door that stood ajar. He concluded that the viscount had at last attained his destination, and was occupied on the task, whatever it was, that had brought him there.
Godfrey, drawing near, ventured to take a peep through the partly-opened door, and caught a glimpse of a large stone chamber, octagonal in shape. From its vaulted roof hung a lighted sconce. No window was visible, and, connecting this circumstance with the number of stairs he had descended, Godfrey was of opinion that it was a subterranean chamber. The floor was devoid of carpet, and the only pieces of furniture were a table of carved oak and four antique chairs of the same material.
