"These are troublous times," said Big Sam, "and I have more than one very good reason to take precautions." "I might suppose so from the change you have made in the entrance to your rooms," I returned. Big Sam gave me a quick glance. "The change is more apparent than real," he said. Then, as if the subject were dismissed, he turned the conversation abruptly. "I believe you wished to see me." The attempt to put me in the position of seeking him, instead of being the one sought, irritated me more than the rude reception I had met on my arrival. "I came," I said sharply, "because I had reason to suppose that you had something to say to me." "I?" said Big Sam in polite surprise. "Yes. I have just received two hundred and fifty dollars on the order you gave me the other day, and, for one thing, I’d like to know what to do with it." "On an order from me?" inquired Big Sam suavely. There was only the blank "no-sabby" mask of China on his face. "Yes," I replied shortly. "It you’ve forgotten our interview in Peter Bolton’s office, maybe this will remind you." And I laid before him the sheet of paper I had received from Kwan Luey. Big Sam glanced at it, and I thought I saw behind the veil of his eyes the shadow of a frown. But if it was there, it was gone in an instant, and he replied blandly: "Ah, you have proved fortunate in the lottery, then." "I was paid two hundred and fifty dollars," was my non-committal answer. "I congratulate you on your good luck." "Thank you," I said sarcastically. "And now I am awaiting my instructions." "Why," said Big Sam slowly, "if you have any scruples about keeping it for yourself, you might apply it to the expenses of the girl you have taken in charge." "That was what I was waiting for," I said. I did not share Big Sam’s pleasure in reaching results by indirect roads, and spoke impatiently. "Is that all you had to say?" "I believe," said Big Sam with ironic courtesy, "that I have some speech still due me. Unless I am much mistaken I have received no report of a certain girl since I delivered her into your hands. Possibly I am wrong in supposing that the circumstances give me any rights." "I dare say I owe you an apology," I said, with swift repentance of my show of temper. "But I understood from what you said in Mr. Bolton’s office that you were in no pressing haste to hear from her." "Pardon me, if I have no recollection of a meeting in Mr. Bolton’s office," said Big Sam dryly. "We shall get on faster if you will kindly assume that it did not take place." The "no-sabby" mask covered his face, as impenetrable as the blank walls of the passageway itself. "As you like," I said. "Then, here is my belated report." And I gave a brief account of the events that had followed the rescue of Moon Ying. At the mention of her wound, Big Sam looked grave, and when I had done he said:
