“It is now well nigh eighteen months since they were first cut off. It is certain that their investment is a very close one, and that the most vigilant watch is used to prevent news of any kind from reaching them from the outside. We have made several efforts to communicate with them, but without success. Some of the messengers we sent never returned, and were, doubtless, detected and killed. Others came back and reported their failure, saying that every avenue to the citadel was so closely watched that it was impossible to get through.”

“Have you any objection, general, to my mentioning this matter to my boy? I am absolutely convinced that he is thoroughly faithful and trustworthy.”

“You may do so if you like, Campbell, though it is hardly likely that he will be able to suggest any method of communication with the garrison that has not already been tried.”

“Thank you, sir.”

The general shortly afterwards went out to wait upon the duchess; in two hours he returned, and as soon as he did so Hector entered his room.

“What is it?” Turenne asked.

“I have been thinking about what you said about the garrison of Turin. I have been talking it over with Paolo, and have come to offer to do my best to deliver a letter from you to the garrison if you will do me the great honour to entrust the mission to me. We both think that two boys would be much more likely to succeed than men. No one would regard them with suspicion; and they could creep and crawl more easily. I do not say that we should succeed, but I think that we should have some chance of doing so. At any rate I am willing to try.”

“It would be a very dangerous expedition,” Turenne said gravely.

“Not more dangerous than going into a battle, viscount. Not a quarter as dangerous as storming a breach.”

Turenne smiled. “The idea has passed through my mind,” he said, “but I should not have proposed it had you not first spoken. It is the sort of mission in which I thought you could be made useful, but it is a rough adventure to begin with, and you must not minimize the danger. It is the duty of a soldier to run the risk of being killed in battle, but it lies beyond his duty to go into the enemy's camp to obtain news. He may volunteer for it, but with a knowledge that if detected he would assuredly be hanged.”
