“You’re some modest violet!” said Muggs.

“Keep quiet, Muggs, and hear the plans,” the Black Star said, his eyes glittering through his mask. “Within the past two months there has been formed in the city a new lodge called the Knights of Certainty. When one understands things that title is rather a good joke. Many good men have heard of the order and wondered why some one did not ask them to join, I presume. The membership was strictly limited. Members of my own band form the lodge.”

“And you’re the supreme boss crook!” Muggs said.

“Another remark, Muggs, and you get the vapor gun. Mr. Verbeck, you’d better warn your man to remain silent!” The Black Star evidently was getting angry.

Muggs turned his head and found his fellow prisoner indicating that he was to be quiet. Muggs obeyed.

“It would be a difficult task to get into a meeting of the Knights of Certainty,” the Black Star went on. “We’re mighty particular who sees things. I may mention that, from the moment we hired our hall and put in furniture, the room has been under close guard, one of our own men even doing the janitor work. This hall is on the third floor of the American Building, adjoining the National Trust Company. We have been making our preparations nightly, of course, working from our hall. Some excellent carpenter and mechanical work has been done, and now, when we wish, we have merely to pass through a wall to a stairway and then make our way over a trail we have prepared to the vaults of the bank and loot them.

“Everything is prepared, I assure you. At this moment my men are in the uniforms of the watchmen, and doing their work. There will be no one to molest us. The vault locks have been fixed so that a few turns of the knobs will unlock them, and yet an expert would swear that time locks and other protections are in perfect working order. It has taken us some time to get this state of affairs prepared, but the reward will be well worth our trouble. The bank received a heavy gold shipment two weeks ago. Negotiable securities are piled in the vaults. The bank, in addition, always carries a heavy cash balance, for it has numerous branches and small affiliated banks. Yes—I fancy we will be well repaid for the work we have put on it.”

“If you get the stuff!” said Muggs.

The Black Star whirled toward him, and one of his men stepped forward, but the master criminal decided to let the remark pass. He walked to the head of the table and glanced at his watch.

“We start in half an hour,” he said. “Number Six, go down to the river and inform Number Ten to be ready to get away instantly.”
