"Dangerous! At least, then, it shall be dangerous to the right person! Give me the letter!"

And, the pistol in his right hand directed at his followers, Aymar held out his left.

"God forgive me!" said de Fresne. The letter changed hands. Aymar replaced the pistol and advanced to the door, and, seeing that he was really coming outside, the men huddled hastily into the sunshine. Aymar followed them.

"Which of you can read?" he asked, looking round.

"You, Goulven, and you, Hervé Le Bihan? Come here, then. You see this letter, which is from M. de Fresne himself—there is his name at the end—and that it is to tell me, as was his duty, of the move he was going to make over the bridge. You can read that, eh? Well, that is all—that is the paper which you foolishly think he was trying to hide."

He kept the letter in his own hands, while, bending over it on either side, with grunts and efforts, the two men laboriously went through its contents, repeating the words aloud, unperturbed by the deciphered passage. And Aymar looked over their heads at the rest and wondered what was going to happen next. To hold them in rein now needed a tight grip, and he was very tired, and more than heartsick. . . .

"Well, are you satisfied?" he asked patiently.

"Yes," said Goulven slowly, "that is what M. de Fresne did—he took us to this place, the bridge of Pont-aux-Rochers. But why did he write it down so that the Blues knew it?"

"I tell you," said the young man, not patiently this time, "that he wrote it to me, while I was away, so that I should know it." And as they bent their heads once more, and tried to peer at the address on the other side, he added, "You can see for yourselves that it was sent to me at Sessignes," and turned over the letter.

As he did so de Fresne, behind him, made, unseen, a gesture of desperation—and Aymar himself turned cold as he saw, on the top left-hand corner of the reverse, a bold endorsement in another hand than de Fresne's . . . "Sent to me by the Vicomte de la Rocheterie, called 'L'Oiseleur', on the night of April 27th, 1815.—A. RICHARD." He shifted his hold of the paper like lightning, so that his left hand covered that corner instead of the lower; but even so the signature was visible. Perhaps the slow minds of his followers would not grasp its meaning. . . .
