"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."
Felix got down a big German atlas, and for half an hour we pored over it. From Bokhara, he said, the only routes for madmen ran to the south. East and north you got into Siberia; west lay the Transcaspian desert; but southward you might go through the Hissar range by Pamirski Post to Gilgit and Kashmir, or you might follow up the Oxus and enter the north of Afghanistan, or you might go by Merv into north-eastern Persia. The first he thought the likeliest route, if a man wanted to travel fast.
I asked him to put in his cable a suggestion about watching the Indian roads, and left him with a promise of early enlightenment.
Then I went down to the Temple, fixed some consultations, and spent a quiet evening in my rooms. I had a heavy sense of impending disaster, not unnatural in the circumstances. I really cannot think what it was that held me to the job, for I don't mind admitting that I felt pretty queasy about it. Partly, no doubt, liking for Tommy and Ethel, partly regret for that unfortunate fellow Pitt-Heron, most of all, I think, dislike of Lumley. That bland super-man had fairly stirred my prosaic antipathies.
That night I went carefully over every item in the evidence to try and decide on my next step. I had got to find out more about my enemies. Lumley I was pretty certain would baffle me, but I thought I might have a better chance with the super-butler. As it turned out I hit his trail almost at once.
Next day I was in a case at the Old Bailey. It was an important prosecution for fraud, and I appeared, with two leaders, for the Bank concerned. The amazing and almost incredible thing about this story of mine is the way clues kept rolling in unsolicited, and I was to get another from this dull prosecution. I suppose that the explanation is that the world is full of clues to everything, and that, if a man's mind is sharp-set on any quest, he happens to notice and take advantage of what otherwise he would miss.
My leaders were both absent the first day, and I had to examine our witnesses alone. Towards the close of the afternoon I put a fellow in the box, an oldish, drink-sodden clerk from a Cannon Street bucket-shop. His evidence was valuable for our case, but I was very doubtful how he would stand a cross-examination as to credit. His name was Routh, and he spoke with a strong North-country accent. But what caught my attention was his face. His jaw looked as if it had been made in two pieces which did not fit, and he had little, bright protuberant eyes. At my first glance I was conscious of a recollection.
He was still in the box when the Court rose, and I informed the solicitors that before going further I wanted a conference with the witness. I mentioned also that I should like to see him alone. A few minutes later he was brought to my chambers, and I put one or two obvious questions on the case, till the managing clerk who accompanied him announced with many excuses that he must hurry away. Then I shut the door, gave Mr. Routh a cigar, and proceeded to conduct a private inquiry.
