A theory was forming in my brain, which I was burningly anxious to put to the test. I remembered how, two years before, I had met Karamaneh near to this same spot; and I had heard Inspector Weymouth assert positively that Fu-Manchu’s headquarters were no longer in the East End, as of yore. There seemed to me to be a distinct probability that a suitable center had been established for his reception in this place, so much less likely to be suspected by the authorities. Perhaps I attached too great a value to what may have been a delusion; perhaps my theory rested upon no more solid foundation than the belief that I had seen Karamaneh in the shop of the curio dealer. If her appearance there should prove to have been phantasmal, the structure of my theory would be shattered at its base. To-night I should test my premises, and upon the result of my investigations determine my future action.
Museum Street certainly did not seem a likely spot for Dr. Fu-Manchu to establish himself, yet, unless my imagination had strangely deceived me, from the window of the antique dealer who traded under the name of J. Salaman, those wonderful eyes of Karamaneh like the velvet midnight of the Orient, had looked out at me.
As I paced slowly along the pavement toward that lighted window, my heart was beating far from normally, and I cursed the folly which, in spite of all, refused to die, but lingered on, poisoning my life. Comparative quiet reigned in Museum Street, at no time a busy thoroughfare, and, excepting another shop at the Museum end, commercial activities had ceased there. The door of a block of residential chambers almost immediately opposite to the shop which was my objective, threw out a beam of light across the pavement, but not more than two or three people were visible upon either side of the street.
I turned the knob of the door and entered the shop.
The same dark and immobile individual whom I had seen before, and whose nationality defied conjecture, came out from the curtained doorway at the back to greet me.
“Good evening, sir,” he said monotonously, with a slight inclination of the head; “is there anything which you desire to inspect?”
“I merely wish to take a look around,” I replied. “I have no particular item in view.”
