Advancing a few paces, he listened intently, and hearing a slight sound in an apartment to the right, he stepped softly towards it, and placing his eye to the keyhole, beheld a tall man, dressed in black, pacing to and fro with rapid strides, while three other persons, wrapped in sable gowns, and disguised with hideous masks, stood silent and motionless at a little distance from him. In the tall man he recognised Cyprian Rougemont. Upon a table in the middle of the room was laid a large open volume, bound in black vellum. Near it stood a lamp, which served to illumine the scene. Suddenly, Rougemont stopped, and turning over several leaves of the book, which were covered with cabalistic characters, appeared in search of some magic formula. Before he could find it, however, a startling interruption occurred. An alarum-bell, fixed against the wall, began to ring, and at the same moment the doors of a cabinet flew open, and a large ape (for such it seemed to Reeks), clothed in a woollen shirt and drawers, sprang forth, and bounding upon the table beside Rougemont, placed its mouth to his ear. The communication thus strangely made seemed highly displeasing to Rougemont, who knitted his brows, and delivered some instructions in an undertone to the monkey. The animal nodded its head in token of obedience, jumped off the table, and bounded back to the cabinet, the doors of which closed as before. Rougemont next took up the lamp, with the evident intention of quitting the room, seeing which, Reeks hastily retreated to an adjoining chamber, the door of which was fortunately open, and had scarcely gained its shelter when the four mysterious personages appeared on the gallery. Reeks heard their footsteps descending the staircase, and then, creeping cautiously after them, watched them across the hall, and pause before the chamber containing Mr. Thorneycroft and his companions. After a moment's deliberation, Rougemont noiselessly locked the door, took out the key, and leaving two of his attendants on guard, returned with the third towards the staircase. Without tarrying to confront them, Reeks started back, and hurried along the gallery till he came to a back staircase, which conducted him, by various descents, to the basement floor, where, after traversing one or two vaults, he entered a subterranean passage, arched overhead, and having several openings at the sides, apparently communicating with other passages. It was lighted at intervals by lamps, which emitted a feeble radiance. By the light of one of these, Reeks discovered the door of a cell. It was of iron, and as he struck it with his hand, returned a hollow clangour. On repeating the blow, a hoarse voice from within cried, "Leave me in peace!" "Is it Auriol Darcy who speaks?" demanded Reeks. "It is," replied the prisoner. "Who are you that put the question?" "A friend," replied Reeks. "I have no friend here," said Auriol.
