I did not look round until I had reached the door; and even then I made a pretence of dropping my keys and stooping to pick them up. The precaution, however, seemed a little superfluous. Mr. Latimer was some thirty or forty yards away, walking inland across the marsh in the direction of Tilbury. I couldn't help wondering whether he had noticed the mast of the Betty, which was just visible in the distance, sticking up demurely above the bank of the creek.
I stepped inside the hut—it was really little more than a hut—and closed the door. The first impression I received was one of being back in my prison cell. The only light in the place filtered in through a tiny and very dirty window, which looked out in the direction that Latimer had taken. For the rest, as soon as my eyes were used to the gloom, I made out a camp bed with blankets on it, a small wooden table and chair, a jug and basin, and in the farther corner of the room a miscellaneous collection of cooking and eating utensils. There was also a large wooden box which I imagined to contain food.
I took in all this practically at a glance, for my mind was still too occupied with my late visitor to trouble much about anything else.
I sat down on the bed and tried to think out the situation clearly. There could be no doubt that Latimer had been spying on the place, if such an unpleasant word could be applied to a gentleman who was supposed to be in Government service. The question was, what did he suspect? I had pretty good evidence that he was up against McMurtrie and the others in some shape or other, and presumably it was on account of my connection with them that I had been favoured with his attentions. Still, this didn't seem to make the situation any the more cheerful for me. If Latimer was really a secret-service man, as some one had told Tommy, it stood to reason that I must be assisting in some particularly shady and dangerous sort of enterprise. I had no special objection to this from the moral point of view, but on the other hand I certainly didn't want to throw away my hardly-won liberty before I had had the satisfaction of settling accounts with George.
I debated with myself whether it would be best to let McMurtrie know that the place was being watched. To a certain extent his interests in the matter seemed to be identical with mine, but my mistrust of him was still strong enough to make me hesitate. Beyond his bare word and that of Sonia I had no proof as yet that he intended to play straight with me.
One thing appeared certain, and that was that Latimer had failed to recognize me as the man who had sent him the warning at Parelli's. In a way this gave me an advantage, but it was a forlorn enough sort of advantage in view of the unknown dangers by which I was surrounded.
I got up off the bed, feeling anything but comfortable, and going to the door had another look round. Latimer had disappeared behind the thin belt of trees that fringed the Tilbury road, and so far as I could see there was no one else about. Getting out my keys, I walked along to the shed and opened the door.
If my living accommodation was a trifle crude, McMurtrie had certainly made up for it here. He had evidently carried out my instructions with the most minute care and an absolute disregard for expense. Lead tanks, sinks, chemicals, an adequate water supply in the shape of a pump—everything I had asked for seemed to have been provided. I looked round the large, clean, well-lighted place with a sensation of intense satisfaction. The mere sight of all these preparations made me ache to begin work, for I was consumed with the impatience that any inventor would feel who had been compelled to leave a big discovery on the very verge of completion.
Coming out, I closed the door again, and carefully turned the key behind me. Then walking back to the hut I locked that up as well. I hadn't the faintest belief in Latimer's story about finding the place open, and apart from making things safe I certainly didn't want to leave any traces of my surprise visit. From what I knew of McMurtrie I felt sure that he had left somebody in charge, and that in all probability Latimer had merely taken advantage of their temporary absence.
After a last glance all round, to make sure that the coast was still clear, I walked rapidly down to the sea-wall and scrambled up on to the top. The tide had risen a bit, but there was just room to get along, so jumping down I set off on my return journey.
