He read a query in my glance.
"Oh! I shall not be late," he added; "I think I may venture out alone on this occasion without personal danger."
Nayland Smith went upstairs to dress, leaving me seated at my writing-table deep in thought. My notes upon the renewed activity of Dr. Fu-Manchu were stacked on my left hand, and, opening a new writing-block, I commenced to add to them particulars of this surprising event in Rangoon which properly marked the opening of the Chinaman's second campaign. Smith looked in at the door on his way out, but seeing me thus engaged, did not disturb me.
I think I have made it sufficiently evident in these records that my practice was not an extensive one, and my hour for receiving patients arrived and passed with only two professional interruptions.
My task concluded, I glanced at the clock, and determined to devote the remainder of the evening to a little private investigation of my own. From Nayland Smith I had preserved the matter a secret, largely because I feared his ridicule; but I had by no means forgotten that I had seen, or had strongly imagined that I had seen, Kâramanèh—that beautiful anomaly who (in modern London) asserted herself to be a slave—in the shop of an antique dealer not a hundred yards from the British Museum!
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 Kâramanèh 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 centre 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 Kâramanèh in the shop of the curio dealer. If her appearance there should prove to have been imaginary, 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.
