"Well, Mr. Holmes, from the moment that I understood that there was something about that suite of rooms which I was not to know, I was all on fire to go over them. It was not mere curiosity, though I have my share of that. It was more a feeling of duty--a feeling that some good might come from my penetrating to this place. They talk of woman's instinct; perhaps it was woman's instinct which gave me that feeling. At any rate, it was there, and I was keenly on the lookout for any chance to pass the forbidden door.
"It was only yesterday that the chance came. I may tell you that, besides Mr. Rucastle, both Toller and his wife find something to do in these deserted rooms, and I once saw him carrying a large black linen bag with him through the door. Recently he has been drinking hard, and yesterday evening he was very drunk; and when I came upstairs there was the key in the door. I have no doubt at all that he had left it there. Mr. and Mrs. Rucastle were both downstairs, and the child was with them, so that I had an admirable opportunity. I turned the key gently in the lock, opened the door, and slipped through.
"There was a little passage in front of me, unpapered and uncarpeted, which turned at a right angle at the farther end.
Round this corner were three doors in a line, the first and third of which were open. They each led into an empty room, dusty and cheerless, with two windows in the one and one in the other, so thick with dirt that the evening light glimmered dimly through them. The centre door was closed, and across the outside of it had been fastened one of the broad bars of an iron bed, padlocked at one end to a ring in the wall, and fastened at the other with stout cord. The door itself was locked as well, and the key was not there. This barricaded door corresponded clearly with the shuttered window outside, and yet I could see by the glimmer from beneath it that the room was not in darkness. Evidently there was a skylight which let in light from above. As I stood in the passage gazing at the sinister door and wondering what secret it might veil, I suddenly heard the sound of steps within the room and saw a shadow pass backward and forward against the little slit of dim light which shone out from under the door. A mad, unreasoning terror rose up in me at the sight, Mr. Holmes. My overstrung nerves failed me suddenly, and I turned and ran--ran as though some dreadful hand were behind me clutching at the skirt of my dress. I rushed down the passage, through the door, and straight into the arms of Mr. Rucastle, who was waiting outside.
