Free The Leithen Stories by John Buchan

from a lettered cabinet a bundle of cards, selected one, and tossed it towards me. It was that of a man of thirty or so, with short side-whiskers and a drooping moustache. The eyes, the ill-fitting jaw, and the brow were those of my friend Mr Tuke, brother and patron of the sorrowful Mr Routh, who had already that afternoon occupied my attention.
    Macgillivray promised to make certain inquiries, and I walked home in a state of elation. Now I knew for certain who had gone to Bokhara, and I knew something, too, of the traveller’s past. A discredited genius was the very man for Lumley’s schemes – one who asked for nothing better than to use his brains outside the ring-fence of convention. Somewhere in the wastes of Turkestan the ex-trade-union official was in search of Pitt-Heron. I did not fancy that Mr Tuke would be very squeamish.
    I dined at the club and left early. Going home, I had an impression that I was being shadowed.
    You know the feeling that some one is watching you, a sort of sensation which the mind receives without actual evidence. If the watcher is behind, where you can’t see him, you have a cold feeling between your shoulders. I daresay it is a legacy from the days when the cave-man had to look pretty sharp to keep from getting his enemy’s knife between the ribs.
    It was a bright summer evening, and Piccadilly had its usual crowd of motor-cars and buses and foot passengers. I haltedtwice, 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 2nd 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 on the lift. Sure enough, a breathlessgentleman appeared, who scanned the street eagerly, and then turned to the lift to watch the
