He wrinkled his brows, lit a Perfecto, and sank again into his accustomed place by the window.

"That policeman wants to see you, sir," said the doorman, suddenly appearing at his elbow. "Says he knows you, and it's somethin' very important."

The clubman smothered a curse. His first impulse was to tell the impudent fellow to go to the devil, but then he thought better of it. He had beaten Conville once, and he would do so again. When it came to a show-down, he reckoned his brains were about as good as a policeman's.

"All right," he replied. "Tell him to sit down—that I've just come in, and will be with him in a few moments."

"Very good, sir," answered the servant.

McAllister perceived that he must think rapidly. There was no escape from the conclusion that he was certainly assisting in the escape of a felon; that he was an accessory after the fact, as it were. The idea did not increase his happiness at all. His one experience in the Tombs, however adventitious, had been quite sufficient. Nevertheless, he could not go back on Wilkins, particularly now that he had promised to assist him. McAllister rubbed his broad forehead in perplexity.

"The officer says he's in a great hurry, sir, and wants to know can you see him at once, sir," said the doorman, coming back.

"Hang it!" exclaimed our hero. "Yes, I'll see him."

He got up and walked slowly to the visitors' room again, while Peter, with a studiously unconscious expression, held the portières open. He entered, prepared for the worst. As he did so, Conville sprang to his feet, leaving a pool of water in front of the sofa and tossing little drops of rain from the ends of his mustache.

"Look here, Mr. McAllister, there's been enough of this. Where's Welch, the crook, who ran in here a few moments ago? Oh, he's here fast enough! I've got your club covered, front and behind. Don't try to con me!"
