As they advanced he heard the doors close with a muffled thunder behind them, and saw that the shadows seemed to retreat and shrink away towards the interior of the house, carrying the hands and faces with them. He heard the wind singing round the walls and over the roof, and its wailing voice mingled with the sound of deep, collective breathing that filled the house like the murmur of a sea; and as they walked up the broad staircase and through the vaulted rooms, where pillars rose like the stems of trees, he knew that the building was crowded, row upon row, with the thronging memories of his own long past. "This is the _House of the Past_," whispered Thorpe beside him, as they moved silently from room to room; "the house of _your_ past. It is full from cellar to roof with the memories of what you have done, thought, and felt from the earliest stages of your evolution until now. "The house climbs up almost to the clouds, and stretches back into the heart of the wood you saw outside, but the remoter halls are filled with the ghosts of ages ago too many to count, and even if we were able to waken them you could not remember them now. Some day, though, they will come and claim you, and you must know them, and answer their questions, for they can never rest till they have exhausted themselves again through you, and justice has been perfectly worked out. "But now follow me closely, and you shall see the particular memory for which I am permitted to be your guide, so that you may know and understand a great force in your present life, and may use the sword of justice, or rise to the level of a great forgiveness, according to your degree of power." Icy thrills ran through the trembling clerk, and as he walked slowly beside his companion he heard from the vaults below, as well as from more distant regions of the vast building, the stirring and sighing of the serried ranks of sleepers, sounding in the still air like a chord swept from unseen strings stretched somewhere among the very foundations of the house. Stealthily, picking their way among the great pillars, they moved up the sweeping staircase and through several dark corridors and halls, and presently stopped outside a small door in an archway where the shadows were very deep. "Remain close by my side, and remember to utter no cry," whispered the voice of his guide, and as the clerk turned to reply he saw his face was stern to whiteness and even shone a little in the darkness. The room they entered seemed at first to be pitchy black, but gradually the secretary perceived a faint reddish glow against the farther end, and thought he saw figures moving silently to and fro. "Now watch!" whispered Thorpe, as they pressed close to the wall near the door and waited. "But remember to keep absolute silence. It is a torture scene."
