It was no good crying over spilt milk, and Lumley's suspicions must be accepted. But I confess that the thought gave me the shivers. The man had a curious terror for me, a terror I cannot hope to analyse and reproduce for you. My bald words can give no idea of the magnetic force of his talk, the sense of brooding and unholy craft. I was proposing to match my wits against a master's, one, too, who must have at his command an organisation far beyond my puny efforts. I have said that my first feeling was that of loneliness and isolation; my second was one of hopeless insignificance. It was a boy's mechanical toy arrayed against a Power-House with its shining wheels and monstrous dynamos. My first business was to get into touch with Tommy. At that time I had a friend in one of the Embassies, whose acquaintance I had made on a dry-fly stream in Hampshire. I will not tell you his name, for he has since become a great figure in the world's diplomacy, and I am by no means certain that the part he played in this tale was strictly in accordance with official etiquette. I had assisted him on the legal side in some of the international worries that beset all Embassies, and we had reached the point of intimacy which is marked by the use of Christian names and by dining frequently together. Let us call him Monsieur Felix. He was a grave young man, slightly my senior, learned, discreet, and ambitious, but with an engaging boyishness cropping up now and then under the official gold lace. It occurred to me that in him I might find an ally. I reached London about eleven in the morning, and went straight to Belgrave Square. Felix I found in the little library off the big secretaries' room, a sunburnt sportsman fresh from a Norwegian salmon river. I asked him if he had half an hour to spare, and was told that the day was at my service. "You know Tommy Deloraine?" I asked. He nodded. "And Charles Pitt-Heron?" "I have heard of him." "Well, here is my trouble. I have reason to believe that Tommy has joined Pitt-Heron in Bokhara. If he has, my mind will be greatly relieved, for, though I can't tell you the story, I can tell you that Pitt-Heron is in very considerable danger. Can you help me?" Felix reflected. "That should be simple enough. I can wire in cypher to the Military Governor. The police there are pretty efficient, as you may imagine, and travellers don't come and go without being remarked. I should be able to give you an answer within twenty-four hours. But I must describe Tommy. How does one do that in telegraphese?" "I want you to tell me another thing," I said. "You remember that Pitt-Heron has some reputation as a Central Asian traveller. Tommy, as you know, is as mad as a hatter. Suppose these two fellows at Bokhara, wanting to make a long trek into wild country--how would they go? You've been there, and know the lie of the land."
