The event entirely failed to justify his misgivings. There could be no doubt that Sir Giles attached serious importance to the contemptible discovery made at the milestone. After having examined and re-examined the fragment, he announced his intention of sending the clerk on a second errand--still without troubling himself to explain what his incomprehensible instructions meant. "If I am not mistaken," he began, "the Reading Rooms, in our town, open as early as nine. Very well. Go to the Rooms this morning, on the stroke of the clock." He stopped, and consulted the letter which lay open on his bed. "Ask the librarian," he continued, "for the third volume of Gibbon's 'Decline and Fall of the Roman Empire.' Open the book at pages seventy-eight and seventy-nine. If you find a piece of paper between those two leaves, take possession of it when nobody is looking at you, and bring it to me. That's all, Dennis. And bear in mind that I shall not recover the use of my patience till I see you again." On ordinary occasions, the head clerk was not a man accustomed to insist on what was due to his dignity. At the same time he was a sensible human being, conscious of the consideration to which his responsible place in the office entitled him. Sir Giles's irritating reserve, not even excused by a word of apology, reached the limits of his endurance. He respectfully protested. "I regret to find, sir," he said, "that I have lost my place in my employer's estimation. The man to whom you confide the superintendence of your clerks and the transaction of your business has, I venture to think, some claim (under the present circumstances) to be trusted." The banker was now offended on his side. "I readily admit your claim," he answered, "when you are sitting at your desk in my office. But, even in these days of strikes, co-operations, and bank holidays, an employer has one privilege left--he has not ceased to be a Man, and he has not forfeited a man's right to keep his own secrets. I fail to see anything in my conduct which has given you just reason to complain." Dennis, rebuked, made his bow in silence, and withdrew. Did these acts of humility mean that he submitted? They meant exactly the contrary. He had made up his mind that Sir Giles Mountjoy's motives should, sooner or later, cease to be mysteries to Sir Giles Mountjoy's clerk. II CAREFULLY following his instructions, he consulted the third volume of Gibbon's great History, and found, between the seventy-eighth and seventy-ninth pages, something remarkable this time. It was a sheet of delicately-made paper, pierced with a number of little holes, infinitely varied in size, and cut with the smoothest precision. Having secured this curious object, while the librarian's back was turned, Dennis Howmore reflected.
