When Langford was alone, he paused for a moment or two to think over his situation; and then, with a natural desire to use the freedom that had been given him, opened the door of the chamber in which he had been placed, and proceeded through the bed-room beyond, to the head of the staircase. Remembering the Earl's request to lock the door, he turned back to do so, and when he again approached the stairs, the voice of some one singing below rose to his ear. The tone in which the singer poured forth his ditty was low, but after listening for a moment, Langford recognised the voice of the poor half-witted man, John Graves, and a sudden hope of finding means of clearing himself by the aid of that very person struck him. He descended the stairs slowly, and at the bottom of the first flight found the wanderer sitting on the lower step, with his head hanging down in an attitude of dejection; laying his hand upon his shoulder, Langford caused him to start up suddenly and turn round. "Ah, Master Harry!" cried the man, in one of his saner moods, "is that you? It is you I came to see. I heard they had taken you up, and locked you up here, and I came to see if I could help you, for you have always been kind and generous to me; and then, if I could not help you, I could sing you a song, and that would do you good, you know; I always said you ought to have your rights, you know; but I must not say so here, or they will scold me, as they did before." "Come up hither with me, John," said Langford; "I believe that you can help me, if you will. But how came you here? Do they suffer you knowingly to wander about the house in this manner?" "Not as far as this," replied the man, laughing; "not as far as this. They would soon drive me down if they saw me above the grand stairs. But about the passages below they never mind me. Only I sometimes creep up, and find my way about all the rooms, and if I hear a step, hide behind a window-curtain. It is no later than last night that I and another--but I must not speak of that. Never you mind, Master Harry, you will have your rights still." "Perhaps so, John," answered Langford, "though I do not think you well know what my rights are. However, now follow me up here." Thus saying, he led the way to the apartments which had been assigned to him, followed quickly by the madman, whose step was as noiseless and stealthy as if he had been going to murder the sleeping. When he saw Langford approach the door of the inner room, he cast an anxious and furtive glance towards the top of the stairs, and listened, and as soon as the lock was turned and the entrance free, he ran in and closed it after him, looking straight towards one of the small cupboards in the wall, saying, "There! there! Be quick, for fear some one should come!" Langford gazed on him with some surprise, and then replied, "You know more of these matters than I thought you did. However, you mistake. I want you merely to bear a letter and a message for me."
