“Escape! my lord —­ escape!  Your eminence does not then know where Monsieur de Beaufort is?”

“Yes, I do, sir; in the donjon of Vincennes.”

“Yes, sir; in a room, the walls of which are seven feet thick, with grated windows, each bar as thick as my arm.”

“Sir,” replied Mazarin, “with perseverance one may penetrate through a wall; with a watch-spring one may saw through an iron bar.”

“Then my lord does not know that there are eight guards about him, four in his chamber, four in the antechamber, and that they never leave him.”

“But he leaves his room, he plays at tennis at the Mall?”

“Sir, those amusements are allowed; but if your eminence wishes it, we will discontinue the permission.”

“No, no!” cried Mazarin, fearing that should his prisoner ever leave his prison he would be the more exasperated against him if he thus retrenched his amusement.  He then asked with whom he played.

“My lord, either with the officers of the guard, with the other prisoners, or with me.”

“But does he not approach the walls while playing?”

“Your eminence doesn’t know those walls; they are sixty feet high and I doubt if Monsieur de Beaufort is sufficiently weary of life to risk his neck by jumping off.”

“Hum!” said the cardinal, beginning to feel more comfortable.  “You mean to say, then, my dear Monsieur la Ramee ——­ "

“That unless Monsieur de Beaufort can contrive to metamorphose himself into a little bird, I will continue answerable for him.”

“Take care! you assert a great deal,” said Mazarin.  “Monsieur de Beaufort told the guards who took him to Vincennes that he had often thought what he should do in case he were put into prison, and that he had found out forty ways of escaping.”

“My lord, if among these forty there had been one good way he would have been out long ago.”

“Come, come; not such a fool as I fancied!” thought Mazarin.

“Besides, my lord must remember that Monsieur de Chavigny is governor of Vincennes,” continued La Ramee, “and that Monsieur de Chavigny is not friendly to Monsieur de Beaufort.”

“Yes, but Monsieur de Chavigny is sometimes absent.”

“When he is absent I am there.”

“But when you leave him, for instance?”

“Oh! when I leave him, I place in my stead a bold fellow who aspires to be his majesty’s special guard.  I promise you he keeps a good watch over the prisoner.  During the three weeks that he has been with me, I have only had to reproach him with one thing —­ being too severe with the prisoners.”

“And who is this Cerberus?”

“A certain Monsieur Grimaud, my lord.”

“And what was he before he went to Vincennes?”

“He was in the country, as I was told by the person who recommended him to me.”

“And who recommended this man to you?”

“The steward of the Duc de Grammont.”
