"I know you are," retorted Guitton coolly, "because I am going to sit beside you and ask you for it till you do!"

"Then you are likely . . . to stay here till . . ." But, game as he was, he could not finish the sentence. He made instead a slight convulsive movement.

"Give me the pencil and paper, Aubert," said the Colonel, undisturbed. "Now, La Rocheterie, we have had enough of this heroic pose. The Moulin Brûlé is very much past history. The sooner you give in the better for yourself. Do you think I am going to move against du Tremblay ignorant of his plans when you, with your penchant for passing on information, are aware of them? I don't enjoy sacrificing my men! . . . This is mainly a number cipher, I see; but I fancy one or two of the words are really cipher, too, eh?"

"I shall not . . ."

"Oh, yes, you will. Suppose you begin by telling me what this number which occurs so frequently represents. You see the one I mean. Don't shut your eyes like that! Two hundred and eighteen—what does two hundred and eighteen represent?"

There was no answer. The face on the pillow was no longer alabaster; it was ashen.

"What does two hundred and eighteen represent, La Rocheterie? I have plenty of time yet; you'll have to tell me in the end. Is it 'river'—'Aven'?"

L'Oiseleur suddenly moved his head as if he could not bear much more, and said sharply to himself, "O God!"

"Ah," commented Guitton in a tone of satisfaction. "You see! in a few minutes you will find yourself telling me all I want to know, and then I will go away and leave you in peace. Perhaps indeed you are already prepared to . . . No? Very well, we will return to our friend two hundred and eighteen. Once more, what does two hundred and eighteen stand for?"

His victim looked up at him desperately and defiantly and shook his head. It made no difference; the query was merely repeated: "What does two hundred and eighteen stand for?"
