"With Avoye's life at stake!" said the Marquis tremulously. "No, you can make of me what you will."
Aymar looked hard at him. Obviously it would really be more convincing that Vaubernier should pretend to have stolen the letter from him, or something of the kind, and should affect to be the person really responsible. . . . No, in spite of his willingness, he could not let him brand himself as a traitor—an old man like that—for the ensuing military coup would hardly clear him, who had no part in it, as it would L'Oiseleur.
"I only want you to be an intermediary," he said firmly. "I propose, Marquis, that you shall strike a bargain with Colonel Richard for my cousin's safety with this letter, which contains important information about the movements of my force to-morrow. It is a letter which I have only just received from my second-in-command. You must assure Colonel Richard that it is genuine, that you have had it straight from me . . . and if he wishes to know how I could bring myself to do such a thing, you must lay stress on the fact that Mme de Villecresne is my cousin. You must not give him the letter till he promises to let Avoye go; it would be better if you could contrive not to interview him with it on you. . . . But I do not ask you to take any responsibility; all that rests on me. You are merely a go-between."
"I understand," said the old gentleman. "And I understand, also, of course, that you intend——"
"You had better understand nothing of the kind," put in Aymar quickly. "Colonel Richard will question you; you must know nothing—nothing—but that I am horribly concerned for Mme de Villecresne's safety—which God knows is true enough!—and you will be prepared to swear that the information is genuine, for I have told you so, on the word of a gentleman."
And, even as he said it, he wondered how much faith Colonel Richard, when he got that letter, would put in the word of a man who could send it.
"Perhaps you had better not know, even, what is in it," he went on, looking down at it. "Indeed, unless one strikes a light, you cannot see. I think that I will seal it up. I can get into the house without being seen."
He went through the open window of the dining-room and lit a candle on the writing-table there. But first he read the letter through again, and realized that place and time, and a little besides, were unintelligible, because they were in cipher. If the letter was to be of any use as a bribe, he must with his own hand decipher these passages. And Aymar hesitated, penetrated through and through with the horrible apparent significance of what he was doing. But it was only apparent; it was only a ruse. And, if he could help it, Avoye should never know the means he was employing to save her; no more than he himself would she like the sound of it. Vaubernier must, if possible, make it a part of the bargain that she should not be told the reason for her release; he must not even see her in person lest she should guess some connection with him, Aymar. And almost more than from Avoye must what he had done for Avoye be kept from his grandmother, who considered already, as he knew, that his cousin had spoilt his life. It was for that reason, not to spare Mme de la Rocheterie's sensibilities, that he hoped even Avoye's danger might not reach her ears. It was just conceivable that Avoye herself, on her return, might keep it from her. If she did not return. . . . But that was unthinkable!
Unthinkable or no, that nightmare thought had him in its grip as he hastily wrote in the words above the cipher. Then he sealed up the letter again with his own seal, and went back into the garden to deliver it to his messenger.
"Sans tache," he said to himself as he went. "Oh, Avoye, my darling!"
