Aubert, who had been detailed to watch Tegelmund, now reported that the latter had been across to the Orleans goods station, inquiring about some heavy cases of goods which had arrived from Lisbon. "I have contrived to open one of the cases," he said. "It contains some complicated and apparently delicate machinery, with a small dynamo. Apparently it is some sort of wireless plant, but, beyond that, I cannot make head or tail of it." At Aubert's suggestion I went late one night to the Orleans goods yard. Aubert, by methods of persuasion not wholly original, had contrived to make friends with one of the officials, and we had no difficulty in securing access to the great goods shed, now silent and deserted, in which the mysterious cases lay. Prising open one end of the topmost case, I inspected the contents as closely as I could with the aid of my pocket flash-lamp. Within was what certainly appeared to be a wireless plant of some kind, but it was of a description entirely new to me, and I could not see enough of it to gain any idea of its purpose. Of course we dared not risk unpacking it. But we had made a great advance. The big cases could not be secretly moved, and our friend, the goods official, undertook to let us know promptly when he received orders to release them. We waited in patience for a week, but still the cases remained untouched and uncalled for. Then came an incident which threw a flood of light on the proceedings of our enemies, though it told us nothing of their real motive; we were to learn that later. One day I was strolling aimlessly along the Boulevard des Capucines, when I heard my name pronounced in accents of delighted surprise. Turning round, I instantly recognised an old friend in the person of Captain A--, who was one of the experts attached to the submarine branch of the British Admiralty. "My dear Sant," he exclaimed joyfully. "Who would have thought of meeting you here? I am alone in Paris. I know no one and am bored to death. What have you got on hand now? I thought you were in New York." "I certainly didn't expect to meet you here," I replied. "What has brought you over?" "Come and have some lunch, and I'll tell you all about it," he replied, and we repaired to an adjoining cafe, where Captain A--promptly ordered lunch in a private room.
