I was marched out of the room with a pistol at each ear.

The storeroom was a damp chamber in what had been the old farmhouse. There was no carpet on the uneven floor, and nothing to sit down on but a school form. It was black as pitch, for the windows were heavily shuttered. I made out by groping that the walls were lined with boxes and barrels and sacks of some heavy stuff. The whole place smelt of mould and disuse. My gaolers turned the key in the door, and I could hear them shifting their feet as they stood on guard outside.

I sat down in that chilly darkness in a very miserable frame of mind. The old boy had gone off in a motor to collect the two ruffians who had interviewed me yesterday. Now, they had seen me as the roadman, and they would remember me, for I was in the same rig. What was a roadman doing twenty miles from his beat, pursued by the police? A question or two would put them on the track. Probably they had seen Mr Turnbull, probably Marmie too; most likely they could link me up with Sir Harry, and then the whole thing would be crystal clear. What chance had I in this moorland house with three desperadoes and their armed servants?

I began to think wistfully of the police, now plodding over the hills after my wraith. They at any rate were fellow-countrymen and honest men, and their tender mercies would be kinder than these ghoulish aliens. But they wouldn’t have listened to me. That old devil with the eyelids had not taken long to get rid of them. I thought he probably had some kind of graft with the constabulary. Most likely he had letters from Cabinet Ministers saying he was to be given every facility for plotting against Britain. That’s the sort of owlish way we run our politics in this jolly old country.

The three would be back for lunch, so I hadn’t more than a couple of hours to wait. It was simply waiting on destruction, for I could see no way out of this mess. I wished that I had Scudder’s courage, for I am free to confess I didn’t feel any great fortitude. The only thing that kept me going was that I was pretty furious. It made me boil with rage to think of those three spies getting the pull on me like this. I hoped that at any rate I might be able to twist one of their necks before they downed me.

The more I thought of it the angrier I grew, and I had to get up and move about the room. I tried the shutters, but they were the kind that lock with a key, and I couldn’t move them. From the outside came the faint clucking of hens in the warm sun. Then I groped among the sacks and boxes. I couldn’t open the latter, and the sacks seemed to be full of things like dog-biscuits that smelt of cinnamon. But, as I circumnavigated the room, I found a handle in the wall which seemed worth investigating.

It was the door of a wall cupboard—what they call a “press” in Scotland—and it was locked. I shook it, and it seemed rather flimsy. For want of something better to do I put out my strength on that door, getting some purchase on the handle by looping my braces round it. Presently the thing gave with a crash which I thought would bring in my warders to inquire. I waited for a bit, and then started to explore the cupboard shelves.

There was a multitude of queer things there. I found an odd vesta or two in my trouser pockets and struck a light. It was out in a second, but it showed me one thing. There was a little stock of electric torches on one shelf. I picked up one, and found it was in working order.

With the torch to help me I investigated further. There were bottles and cases of queer-smelling stuffs, chemicals no doubt for experiments, and there were coils of fine copper wire and yanks and yanks of thin oiled silk. There was a box of detonators, and a lot of cord for fuses. Then away at the back of the shelf I found a stout brown cardboard box, and inside it a wooden case. I managed to wrench it open, and within lay half a dozen little grey bricks, each a couple of inches square.

I took up one, and found that it crumbled easily in my hand. Then I smelt it and put my tongue to it. After that I sat down to think. I hadn’t been a mining engineer for nothing, and I knew lentonite when I saw it.
