"And what was the other paper he spoke of?" asked Blagden. "What did he call it? 'The holy of holies'?"

Atherton started to draw it from his pocket; then, with an apologetic half laugh, thrust it back again, walked to the door, and cautiously reconnoitered. But no one was in sight, and accordingly he rejoined his friends, again pulling the envelope from its resting place, while Mills and Blagden peered eagerly over his shoulder. The first envelope contained a second one; the second a third. "April fool," muttered Mills. "I told you he was crazy," but was suddenly silent as Atherton drew from the third envelope the paper, faded and yellow with age, which Bellingham had found in the vault, and with it a typewritten copy, explaining its contents as far as the secretary had been able to decipher them. No faintest sound disturbed the stillness of the room as they read, and as they finished, they remained motionless, staring at each other, with all trace of levity or disbelief gone suddenly from their faces. Then Mills, like a man awakening from a trance, slowly passed his hand across his forehead. "He couldn't have faked that paper," he murmured. "That's the real thing."

But the others scarcely heard him. "Then it is true," said Atherton at length. "Everything we've heard and guessed at, but never honestly believed. There is a 'Money Trust,' there is a 'System.' Good Lord, it's like a dream!"

"A nightmare," responded Blagden grimly. "No wonder we couldn't win. And now let's take our time, and go over it again. I should say that 'holy of holies' was right; I believe this scrap of paper is just about the most important document in the world."

Side by side, they seated themselves at the table, and word by word began their study of the cryptic talisman. Half way through Atherton called a halt. "So far, so good," he observed. "As Bellingham told us, it's the very height of simplicity. They feed the public with good news, bait them with bull tips, and then when a sufficient number have loaded up at the top, they break the market and incidentally break the fools who have been caught. Then begins the campaign of bad news--famine, pestilence and sudden death--then arrive the bear tips, and when all the longs have been driven out and a new crop of suckers have gone short at the bottom, then comes the accumulation by the Money Gods and up goes the market for them to sell on to the next crop of idiots who will never buy except at the very top, after stocks have advanced from ten to twenty points. But all that doesn't help us much, unless we can tell what is the bottom and what is the top. What we want to know is about these signals. Signals on the tape. What a wonderful scheme! When Bellingham found this paper, he must have felt as if he had happened upon a ton of dynamite."

"Dynamite," said Blagden, "is a very happy word. If we could prove the authenticity of this paper, we could just about blow this old country sky-high. We could close every stock exchange in America, and drive the Money Gods into exile for their health. Oh, 'dynamite' is too mild a word; this would be a higher explosive than that."

As he finished speaking, Atherton was conscious of a sudden chill of dismay. Rightly or wrongly, he had no desire to see harm befall Helen Hamilton's father, and was correspondingly relieved to hear Mills exclaim, "Yes, but we don't want to do anything like that. The only time to be reformers is when we've made all the money we can use. We want ours, Blagden, so for Heaven's sake don't think of blowing this thing until we've had a chance at it."

Blagden smiled at the stout man's earnestness. "Oh, don't worry," he reassured him. "I was only emphasizing the importance of the paper. You are quite right, Tubby; let the Money Gods live and wax fat. All we want is a few of the crumbs that fall from the master's table."

"Sure thing," Atherton assented with relief, "we're all agreed about that. And now let's examine the rest of the paper. The signals themselves; that's what interests us."

Once more they bent to their task. "On the watch," read Mills, "for these signals. Now what is the sense in that? Of course they would be on the watch for them. They would be fools not to."
