Now I am a sober and practical person, but, slender though my evidence was, it brought to my mind the most absolute conviction. I seemed to know Pitt-Heron's story as if I had heard it from his own lips--his first meeting with Lumley and their growing friendship; his initiation into secret and forbidden things; the revolt of the decent man, appalled that his freakishness had led him so far; the realisation that he could not break so easily with his past, and that Lumley held him in his power; and last, the mad flight under the pressure of overwhelming terror. I could read, too, the purpose of that flight. He knew the Indian frontier as few men know it, and in the wild tangle of the Pamirs he hoped to baffle his enemy. Then from some far refuge he would send for his wife and spend the rest of his days in exile. It must have been an omnipotent terror to drive such a man, young, brilliant, rich, successful, to the fate of an absconding felon. But Lumley was on his trail. So I read the telegram I had picked up on the floor of the Blackheath house, and my business was to frustrate the pursuit. Some one must have gone to Bokhara, some creature of Lumley's, perhaps the super-butler I had met in the County Court. The telegram, for I had noted the date, had been received on the 27th day of May. It was now the 15th of June, so if some one had started immediately on its receipt, in all probability he would by now be in Bokhara. I must find out who had gone and endeavour to warn Tommy. I calculated that it would have taken him seven or eight days to get from Moscow by the Transcaspian; probably he would find Pitt-Heron gone, but inquiries would set him on the track. I might be able to get in touch with him through the Russian officials. In any case, if Lumley were stalking Pitt-Heron, I, unknown and unsuspected, would be stalking Lumley. And then in a flash I realised my folly. The wretched letter I had written that morning had given the whole show away. Lumley knew that I was a friend of Pitt-Heron, and that I knew that he was a friend of Pitt-Heron. If my guess was right, friendship with Lumley was not a thing Charles was likely to confess to, and he would argue that my knowledge of it meant that I was in Charles's confidence. I would therefore know of his disappearance and its cause, and alone in London would connect it with the decorous bachelor of the Albany. My letter was a warning to him that he could not play the game unobserved, and I, too, would be suspect in his eyes.
