I arrived somewhat late at the appointed rendezvous, and found Madame Jaubert in a state of manifest excitement and impatience. She had, she was pretty sure, discovered Armstrong, and knew that he was at that moment in a house in Greek Street, Soho. "Greek Street, Soho! Is he alone?" "Yes; with the exception of a woman who is minding the premises, and of whom he is an acquaintance under another name. You will be able to secure him without the least risk or difficulty, but not an instant must be lost." Madame Jaubert perceived my half-hesitation. "Surely" she exclaimed, "you are not afraid of one man! It's useless affecting to suspect _me_ after what has occurred." "True," I replied. "Lead on." The house at which we stopped in Greek Street appeared to be an empty one, from the printed bills in the windows announcing it to be let or sold. Madame Jaubert knocked in a peculiar manner at the door, which was presently opened by a woman. "Is Mr. Brown still within?" Madame Jaubert asked in a low voice. "Yes: what do you want with him?" "I have brought a gentleman who will most likely be a purchaser of some of the goods he has to dispose of." "Walk in, then, if you please," was the answer. We did so; and found ourselves, as the door closed, in pitch darkness. "This way," said the woman; "you shall have a light in half a minute." "Let me guide you," said Madame Jaubert, as I groped onwards by the wall, and at the same time seizing my right hand. Instantly as she did so, I heard a rustle just behind me--two quick and violent blows descended on the back of my head, there was a flash before my eyes, a suppressed shout of exultation rang in my ears, and I fell insensible to the ground.
