On the landing they were confronted by a number of doors, one of which the old German threw open. They entered a large, plainly furnished, well-lit room, looking pretty much like a merchant's office, though the walls were mostly hung with maps and plans of foreign cities. Brand looked round with a supercilious air. All his pleasant and friendly manner had gone. He was evidently determined to make himself as desperately disagreeable as an Englishman can make himself when introduced to a foreigner whom he suspects. But even he would have had to confess that there was no suggestion of trap-doors or sliding panels in this ordinary, business-like room; and not a trace of a dagger or a dark lantern anywhere. Presently, from a door opposite, an elderly man of middle height and spare and sinewy frame walked briskly in, shook hands with Lord Evelyn, was introduced to the tall, red-bearded Englishman (who still stood, hat in hand, and with a portentous stiffness in his demeanor), begged his two guests to be seated, and himself sat down at an open bureau, which was plentifully littered with papers. "I am pleased to meet you, Mr. Brand," he said, speaking carefully, and with a considerable foreign accent. "Lord Evelyn has several times promised me the honor of making your acquaintance." Mr. Brand merely bowed: he was intent on making out what manner of man this suspected foreigner might be; and he was puzzled. At first sight Ferdinand Lind appeared to be about fifty or fifty-five years of age; his closely cropped hair was gray; and his face, in repose, somewhat care-worn. But then when he spoke there was an almost youthful vivacity in his look; his dark eyes were keen, quick, sympathetic; and there was even a certain careless ease about his dress--about the turned-down collar and French-looking neck-tie, for example--that had more of the air of the student than of the pedant about it. All this at the first glance. It was only afterward you came to perceive what was denoted by those heavy, seamed brows, the firm, strong mouth, and the square line of the jaw. These told you of the presence of an indomitable and inflexible will. Here was a man born to think, and control, and command. "With that prospect before me," he continued, apparently taking no notice of the Englishman's close scrutiny, "I must ask you, Mr. Brand--well, you know, it is merely a matter of form--but I must ask you to be so very kind as to give me your word of honor that you will not disclose anything you may see or learn here. Have you any objection?" Brand stared, then said, coldly, "Oh dear, no. I will give you that pledge, if you wish it." "It is so easy to deal with Englishmen," said Mr. Lind, politely. "A word, and it is done. But I suppose Lord Evelyn has told you that we have no very desperate secrets. Secrecy, you know, one must use sometimes; it is an inducement to many--most people are fond of a little mystery; and it is harmless."
