Considering it was nearly the height of the London winter season, the Great Empire Hotel was not unusually crowded. This might perhaps have been owing to the fact that two or three of the finest suites of rooms in the building had been engaged by Mark Fenwick, who was popularly supposed to be the last thing in the way of American multi-millionaires. No one knew precisely who Fenwick was, or how he had made his money; but during the last few months his name had bulked largely in the financial Press and the daily periodicals of a sensational character. So far, the man had hardly been seen, it being understood that he was suffering from a chill, contracted on his voyage to Europe. Up to the present moment he had taken all his meals in his rooms, but it was whispered now that the great man was coming down to dinner. There was quite a flutter of excitement in the Venetian dining-room about eight o'clock. The beautifully decorated saloon had a sprinkling of well-dressed men and women already dining decorously there. Everything was decorous about the Great Empire Hotel. No thought had been spared in the effort to keep the place quiet and select. The carpets were extra thick, and the waiters more than usually soft-footed. On the whole, it was a restful place, though, perhaps, the decorative scheme of its lighting erred just a trifle on the side of the sombre. Still, flowers and ferns were soft and feathery. The band played just loudly enough to stimulate conversation instead of drowning it. At one of the little tables near the door two men were dining. One had the alertness and vigor which bespeaks the dweller in towns. He was neatly groomed, with just the slight suspicion of the dandy in his dress, though it was obvious at the merest glance that he was a gentleman. His short, sleek hair gave to his head a certain suggestion of strength. The eyes which gleamed behind his gold-rimmed glasses were keen and steady. Most men about town were acquainted with the name of Jim Gurdon, as a generation before had been acquainted with his prowess in the athletic field. Now he was a successful barrister, though his ample private means rendered professional work quite unnecessary. The other man was taller, and more loose-limbed, though his spare frame suggested great physical strength. He was dark in a hawk-like way, though the suggestion of the adventurer about him was softened by a pair of frank and pleasant grey eyes. Gerald Venner was tanned to a fine, healthy bronze by many years of wandering all over the world; in fact, he was one of those restless Englishmen who cannot for long be satisfied without risking his life in some adventure or other.
