The way was long, with many sharp turns. It seemed to be a space between rooms. Once or twice shouts and laughter were faintly heard, as they seemed to pass near a room full of soldiers. It was dark. The girl ahead felt in her pocket, and brought out a tiny flashlight. They came finally to a steep flight of stairs.

Now for the first time the girl spoke. In a cautious whisper she said, "Be careful!" and holding the flash behind her for their guidance, went swiftly and lightly down, with the manner of one who is familiar with every inch of the way. The stairs were wide and shallow. There were a great many of them and they seemed to go down a long way. Evelyn wondered if the place was built on a hillside, making it a long way to the underground regions she suspected beyond or below. She afterwards found out that this was correct. A door barred with iron was at the foot of the stairs. Indeed, they ended right against it. The girl pushed the door open, and when they had entered, closed it behind them and dropped a massive bar across it. They were in a large, stone chamber, empty save for a few scraps of furniture.

Their guide swiftly crossed the room and opened another forbidding looking door. The second room was like the first, but was filled with casks and huge barrels. Beyond this again they entered a narrow passage, so very narrow that their garments brushed the walls at either side. The stones underfoot were rough and uneven.

Professor Morris walked carefully, picking his steps by the aid of the flashlight. Evelyn and Jack, more careless, stumbled frequently, but still the girl, light as a feather, flitted on, swift and sure footed.

Once more the flash revealed a wall ahead. As she approached it the girl turned and smiled. Evelyn stared. There was no sign of any opening in the rough wall and the great stones seemed fast in their cement, but the girl, stooping, pressed a corner of one of the paving stones. To their amazement it slid from its place, revealing another very narrow flight of steps. The girl descended, and when they were all down, pressed another spring, and the stone slid in place. Another flight of steps exactly like the ones they had just descended rose against the flooring; and when the girl had led the way, they one by one stepped into a large and brightly lighted room.

Professor Morris blinked; Jack turned red; Evelyn gasped with surprise.

CHAPTER VIII

THE SECRET CHAMBER

It was a vast apartment of stone, but the rugged walls were nearly covered with the most rare and beautiful hangings—curtains, tapestries and strange oriental rugs. Numerous paintings apparently of great value also hung about, or stood on the floor leaning against the wall. The stone floor was deep with rugs and fine furs. A number of couches, wide and comfortable, were set here and there, and one corner of the room was hidden by a great black and gold screen. From this corner came the comforting odor of coffee.

Professor Morris sniffed it with joy.
