One of the Black Star's band happened to overhear the boast, for the men and women working for the Black Star were to be found in all walks of life, and there was nothing strange in the fact that one of them happened to be a guest at an exclusive social affair. At one stage of the game even Verbeck himself had been suspected of being a lieutenant of the master criminal.

The Black Star had challenged Verbeck to make good his boast, and there had ensued a duel of wits. Whereas the master rogue had an organization at his command, Verbeck had nobody except Muggs.

Muggs was a peculiar individual. Years before, Muggs had stood on a bridge over the Seine, in Paris, ready to fling himself into the water and end an existence that, in a fit of despondency, he had decided was not worth carrying out to its logical conclusion.

Roger Verbeck had grasped him by the arm in time to save him, and had convinced Muggs that life was worth the living. So Muggs became attached to Roger Verbeck. He was known as Verbeck's valet, but he was a comrade-in-arms in reality. He shared Verbeck's adventures, and often turned failure into success. He was ready to fight for Verbeck at any moment.

Muggs had worked with Verbeck against the Black Star, and when the master criminal finally was captured and incarcerated, Muggs had turned valet again. But Muggs was a man who demanded action, and time hung heavy on his hands. For Roger Verbeck was thinking of getting married, and he had small time for adventuring.

Muggs was a small man, but one of great strength. There was nothing handsome about him. Some called him repulsive, but not in Roger Verbeck's hearing.

Muggs had been a criminal and knew the ways of criminals. He had been of great value to Verbeck on numerous occasions, and once had saved his life. Between them they possessed nearly all human qualifications, and they made an excellent team.

On the night of the rescue of the Black Star, Roger Verbeck had called upon his fiancée. He returned to his rooms shortly after the hour of twelve, and immediately went to bed, Muggs retiring a few minutes later. There was to be a golf tournament the following day, and Verbeck was a contestant.

Both men were asleep almost immediately. Most of the tenants in the big apartment house had retired. In the office on the ground floor a sleepy clerk was attempting to keep his eyes open and read a magazine. The night telephone operator had gone to a restaurant a couple of blocks away for a midnight cup of coffee, and the sleepy clerk was watching the switchboard.

There entered a gentleman from the street—a man whose face was muffled in his coat collar. He was well-dressed, very much the gentleman, and the clerk got up and hurried to the desk. Somebody with an important business message for one of the tenants, the clerk supposed.
