It was a bright summer evening, and Piccadilly had its usual crowd of motor-cars and busses and foot passengers. I halted twice, once in St. James's Street and once at the corner of Stratton Street, and retraced my steps for a bit, and each time I had the impression that some one a hundred yards or so off had done the same. My instinct was to turn round and face him, whoever he was, but I saw that that was foolishness. Obviously in such a crowd I could get no certainty in the matter, so I put it out of my mind.
I spent the rest of the evening in my rooms, reading cases and trying to keep my thoughts off Central Asia. About ten I was rung up on the telephone by Felix. He had had his answer from Bokhara. Pitt-Heron had left with a small caravan on June 2d by the main road through the Hissar range. Tommy had arrived on June 10th and on the 12th had set off with two servants on the same trail. Travelling the lighter of the two, he should have overtaken Pitt-Heron by the 15th at latest.
That was yesterday, and my mind was immensely relieved. Tommy in such a situation was a tower of strength, for, whatever his failings in politics, I knew no one I would rather have with me to go tiger-shooting.
Next day the sense of espionage increased. I was in the habit of walking down to the Temple by way of Pall Mall and the Embankment, but, as I did not happen to be in Court that morning, I resolved to make a detour and test my suspicions. There seemed to be nobody in Down Street as I emerged from my flat, but I had not walked five yards before, turning back, I saw a man enter from the Piccadilly end, while another moved across the Hertford Street opening. It may have been only my imagination, but I was convinced that these were my watchers.
I walked up Park Lane, for it seemed to me that by taking the Tube at the Marble Arch Station I could bring matters to the proof. I have a knack of observing small irrelevant details, and I happened to have noticed that a certain carriage in the train which left Marble Arch about 9.30 stopped exactly opposite the exit at the Chancery Lane Station, and by hurrying up the passage one could just catch the lift which served an earlier train and so reach the street before any of the other travellers.
I performed this manoeuvre with success, caught the early lift, reached the street and took cover behind a pillar-box from which I could watch the exit of passengers from the stairs. I judged that my tracker, if he missed me below, would run up the stairs rather than wait for the lift. Sure enough, a breathless gentleman appeared, who scanned the street eagerly, and then turned to the lift to watch the emerging passengers. It was clear that the espionage was no figment of my brain.
I walked slowly to my chambers and got through the day's work as best I could, for my mind was preoccupied with the unpleasant business in which I found myself entangled. I would have given a year's income to be honestly quit of it, but there seemed to be no way of escape. The maddening thing was that I could do so little. There was no chance of forgetting anxiety in strenuous work. I could only wait with the patience at my command, and hope for the one chance in a thousand which I might seize. I felt miserably that it was no game for me. I had never been brought up to harry wild beasts and risk my neck twice a day at polo like Tommy Deloraine. I was a peaceful, sedentary man, a lover of a quiet life, with no appetite for perils and commotions. But I was beginning to realize that I was very obstinate.
At four o'clock I left the Temple and walked to the Embassy. I had resolved to banish the espionage from my mind, for that was the least of my difficulties.
Felix gave me an hour of his valuable time. It was something that Tommy had joined Pitt-Heron, but there were other matters to be arranged in that far country. The time had come, in my opinion, to tell him the whole story.
The telling was a huge relief to my mind. He did not laugh at me as I had half feared, but took the whole thing as gravely as possible. In his profession, I fancy, he had found too many certainties behind suspicions to treat anything as trivial. The next step, he said, was to warn the Russian police of the presence of the man called Saronov and the super-butler. Happily we had materials for the description of Tuke or Routh, and I could not believe that such a figure would be hard to trace. Felix cabled again in cypher, asking that the two should be watched, more especially if there was reason to believe that they had followed Tommy's route. Once more we got out the big map and discussed the possible ways. It seemed to me a land created by Providence for surprises, for the roads followed the valleys, and to the man who travelled light there must be many short cuts through the hills.
