CHAPTER VIII THE CATACOMBS OF PARIS Here was a way of escape, but escape to where? He did not consider the latter question for an instant. Replacing the lamp on the table, he glanced round to make sure that everything was in exact order, counted all the articles in his possession, the _crochet_, the two extra candles which he carried, etc., just as a surgeon counts the sponges which he has used during an operation, and having satisfied himself that he had disturbed nothing and left nothing behind, he extinguished the lamp, found the trap-door opening in the darkness and came down the ladder. It had fifteen rungs. When he felt the solid ground under his feet, he lit one of his candles and looked about him. He was standing in a passage that led to a flight of steps descending into darkness, above was the square opening of the trap-door, and shining in the wall on his right, a brass handle. He guessed its use and pulling on it, the flap of the door above rose steadily and slowly and closed with a faint sucking sound like that of a piston driven home in a perfectly fitting cylinder. It seemed to Lavenne that everything was favouring him, for had he been forced to leave the door open, his plan might have been ruined, as Camus would undoubtedly have suspected a spy on his movements. With the lighted candle in his hand, he came towards the flight of steps. At the top of this stone stairway, he paused for a moment almost daunted. It seemed to have no end. The light of the candle became swallowed up in the darkness before revealing the last step. There were over a hundred of these steps leading to a passage, or rather a tunnel, which ended by opening into a corridor. The tunnel struck the corridor at right angles, and Lavenne, holding his light to the walls, looked in vain for an indication as to whether he should turn to the right or the left. Failing to find any, he turned to the right. He had gone only a few yards when an opening in the corridor wall gave him a glimpse of something more daunting than the darkness. It was a skull resting on a heap of bones. The skull, from which the lower jaw was missing, was yet not wholly without speech. It told Lavenne at once where he was. Pursuing his way and casting the light of the candle into several more of these lidless sarcophagi, he reached a large open space, where over the piles of bones heaped against the walls, the candle-light revealed a Latin inscription cut into the stone. From this open space to the right, to left, in front and behind of the man who had just entered it, the candle-light showed four corridors each leading to darkness. Lavenne had left the laboratory of Count Camus only to find himself entangled in the Catacombs of Paris.
