"I dressed as quickly as I could, ran down the stairs and jumped into the waiting cab. The door banged and we started off. The engines must have been running, for we went away like a flash. There was some one else sitting there. A hand clapped over my mouth and an arm round my body. I couldn't move or speak. Then the thumb of the hand did something to the big nerves behind my ear. It's an Oriental trick and I had just realized it when something wet and sweet was pressed over my mouth and nose, and I lost all consciousness.
"When I woke up I found myself in a fair-sized room, lit by a skylight high up in the roof. There was a bed, a table, a chair, and various other conveniences, and I hadn't the slightest idea where I could be. My head ached and I felt bruised all over, so I drank a glass of water, crawled back into the bed and slept. When I woke again there was an affable Chink sitting by my side, who spoke quite good English.
"'You will,' he said, 'be kept here for some time in durance, yess. It's an unfortunate necessity, yess.'
"I heard on all sides familiar noises. I knew in a moment what had happened. I had been brought back to the works at the base of the three towers."
"All this fits in very well with what I now know, Rolston. I'll tell you everything in a minute, but I want to hear your story first."
"Very good, Sir Thomas. For over three months I've been kept a prisoner at Richmond. I wasn't badly treated. I had anything I liked to eat and drink, any books to read—tobacco, a bath—everything but newspapers, which were rigidly denied me. I wasn't kept entirely to my prison room. I was allowed to go out and take exercise within the domain surrounded by the great thirty-foot wall, though I was never let to roam about as I wished. There was always a big Chinese coolie with a leaded cane attending me, a man that only spoke a few words of English.
"Now, Sir Thomas, please remember this. From first to last none of my jailers knew that I understood Chinese. And none of them knew or suspected that I had been among the workmen before, in order to get materials for the scoop with which I came to you."
I saw the value of that at once.
"Good for you, Rolston; now please continue."
"Well, Sir Thomas, I kept my eyes and ears very wide open and I learnt a lot. Things were being prepared with a feverish activity of which the people outside had not the slightest idea. I found that round the base of the towers, in the miniature park inclosed by the high wall, there were already magnificent vegetable gardens in active being. There were huge conservatories which must have been set up when the towers were only a few hundred feet high, now full of the rarest flowers and shrubs. In my walks, I saw a miniature poultry farm, conducted on the most up-to-date methods; there was a dairy, with four or five cows—already this part of the huge inclosure was assuming a rural aspect. It must have been planned and started nearly two years ago."
