But Rouletabille beckoned our group into the garden and announced to us in a jesting tone that if any of us had any desire to make a trip to the village, we must give it up for that evening, for the order had gone forth and no one could leave the château or enter it. Pere Jacques, he added, still pretending to jest, was charged with the carrying out of the command, and everyone knew that it was impossible to bribe the faithful old servitor. It was then that I learned for the first time that Pere Jacques, whom I had known so well at the Glandier, had accompanied Professor Stangerson on his visit and was acting as his valet. That night he was sleeping in a tiny closet in “la Louve,” near his master’s bed room, but Rouletabille had changed that, and it was Pere Jacques who took the place of the concierges in the tower marked A. “But where are the Berniers?” cried Mme. Edith. “They are installed in the Square Tower, in the room on the left, near the entrance; they are to act as caretakers of the Square Tower,” replied Rouletabille. “But the Square Tower doesn’t need any caretakers!” exclaimed Edith, whose vexation was plainly visible. “That, Madame,” returned the young reporter, “is what we cannot be sure of.” He made no further explanations, but he took M. Arthur Rance to one side and informed him that he ought to tell his wife about the reappearance of Larsan. If there was to be the slightest chance of hiding the truth from M. Stangerson, it could scarcely be accomplished without the aid and intelligence of Mme. Edith. And, then, too, it would be as well, henceforward, for all of those in the Fort of Hercules to be prepared for everything, _and surprised at nothing_! The next act of Rouletabille was to make us walk across the court and place ourselves at the postern of the gardener. I have said that this postern (H) commanded the entrance to the inner court; but at that point the moat had been filled up a long time ago. Rouletabille, to our amazement, declared that the next day he intended to have the moat dug out and to replace the drawbridge. For the present, he busied himself with ordering the postern to be closed more securely by the servants of the château by means of a sort of fortification built from the boards and bricks which had been used in the repairs of the château, and which had not yet been taken away by the workmen. Thus the château was barricaded and Rouletabille laughed softly to himself, for Mme. Edith, having been apprised by her husband of the facts of the case, made no further objection, but contented herself with smiling a little contemptuously at the timidity of her guests, who were transforming the old stronghold into an absolutely impenetrable spot, because they were afraid of just one man--one man, all alone. But Mme. Edith did not know what manner of man this was. She had not lived through the mysteries of the yellow room.
