“That order no longer exists. Monsieur Merriwell, you need have no further fear of the league.”

“How about the tools of the league?”

“They are harmless now, for the league is not behind them. There is no reason why they should molest you.”

There was a scream, and a sudden commotion at the adjoining table. Several gendarmes had appeared there, and they were arresting the man and the woman. The man was furious, and made a struggle. He tried to draw a weapon and place it at his head, plainly with the intention of committing suicide, but he was prevented and disarmed. Then irons were placed upon him. A hand fell on Frank Merriwell’s arm. He turned his head, and saw the Man of Mystery at his elbow.

“You have witnessed the arrest of the chief of the Black Brothers!” said Mr. Noname, with great satisfaction. “I have hunted him down! I have placed the officers upon him!”

“You?”

“Yes! The band is scattered and broken. One has committed suicide to-night, while two others have been arrested. Three have fled from Paris. My hired spies have done their work swiftly and well!”

“And you have brought all this about?”

“Even so. More than that, I have solved the mystery of the bomb-throwing. In a drawer of the very table at which the man sat, drinking coffee and reading a paper, when you rushed into the café to capture the bomb-thrower, I discovered—these!”

He held up a false beard, a long-haired wig, and a slouch hat.
