For some reason or other the place affected me most unpleasantly, and it was with a little shudder that I retreated and skirted the fence which guarded the dangerous part of the cliff. When I had passed by this, the path turned at right angles and went inland. As I turned I saw, perhaps a furlong away, the house of Helzephron. It lay upon the eastern slope of Carne Zerran, an ancient, grim-looking house of granite, long, low, and of considerable size. A few stunted trees grew round about, and a fairly extensive domain of gardens, as I supposed, surrounded by a high wall. Using my prism glasses, I could see that this wall was topped by iron spikes. Of course, I was considerably below Tregeraint as on the sloping hill-side, and it lay quite open to view. Higher up, and beyond the house, was the derrick, engine-house and sheds of the mine, with here and there dumps of débris and various sheds. Although the wire fences, which I soon made out, went round the whole property, it lay quite open to the view. And when I had passed it, and climbed to the table-land of the moor beyond, I saw that it would be even more open to the eyes--spread out like a map, in short. One thing was already certain. There was nothing whatever in the nature of a hangar, no building that could possibly shelter even an ordinary four or five seater biplane, to say nothing of an air cruiser. I was not disappointed, because I had hardly expected to meet with anything of the kind. The pirate ship, you will remember, was--like all the big long-distance airships--a cross between what used to be known in the old days as the "seaplane" and the "flying-boat." True, some of our war aeroplanes of quite large size were fitted with floats that could be raised, and wheels for land work in addition. This might be the case with the pirate. But it was not to be thought of for a moment that a man of Helzephron's intelligence would dare to house his extraordinary ship where any one of my police could have investigated simply by showing his badge of office. The land policeman and the coastguards of the whole English coastline had already reported on every hangar and aerodrome in the kingdom. If Helzephron was the man I believed him, I was well aware that we were only at the beginning of the duel. I mounted up past the wire fences and the mine. I did not dare to use my glasses in passing, for I saw in the distance one or two figures of men strolling about by the engine-house and derrick. But when I was at last among the heather at the top, I lay down, and took a long survey of the buildings, drawing a careful map in my pocket-book, which might prove of great use later on. I waited half an hour at the little station of St. Erth, and then caught a train to Penzance, arriving at the hotel about tea-time. As I came into the lounge, after a wash and brush up, I saw Danjuro sitting in one corner. He had a pile of newspapers round him, and I saw that the London journals had arrived.
