The hand-clasp broke. Leclair began:

"As for you, monsieur, I already know you, of course. You are—"

The Master raised a palm of protest.

"Who I am does not matter," said he. "I am not a man, but an idea. My personality does not count. All that counts is the program, the plan I stand for.

"Many here do not even know my name. No man speaks it. I am quite anonymous; quite so. Therefore I pray you, keep silent on that matter. What, after all, is the significance of a name? You are an ace, an officer. So am I."

"True, very true. Therefore I more keenly regret the fact that I must place you under arrest, and that charges of piracy in the high air must be lodged against you."

"Thank you for the regret, indeed," answered the Master dryly. Save for the fact that this strange man never laughed and seldom smiled, one would have thought the odd twinkle in his eye prefaced merriment. "Well, what now?"

The Frenchman produced a silver cigarette-case, opened it and extended it toward the man now technically his prisoner. As yet he had said no word concerning the tremendous execution done the air police forces. His offer of the cigarettes was as calm, as courteous as if they two had met under circumstances of the most casual amity. The Master waved the cigarettes away.

"Thank you, no," said he. "I never smoke. But you will perhaps pardon me if I nibble two or three of these khat leaves. You yourself, from your experience in Oriental countries, know the value of khat."

"I do, indeed," said the other, his eyes lighting up.
