“And you are not even curious to know what brought me here again?” he continued, in the same tone.

“Some act of folly, I do not doubt,” said Maison-Rouge, his face clearing a little. “You will never learn discretion.”

“Ah, but this is far less serious,” cried Richelieu. “Before, I offended the prudery of Madame de Maintenon, who was trying to turn Louis into a monk and the court into a priory. This time I have merely killed one of the regent’s friends. The regent is a man, and will soon forgive.”

“I trust so,” and Maison-Rouge glanced at him with the shadow of a smile. “I have no reason to wish you ill, M. le Duc.” Evidently, the winning good humor of my companion had touched even this enfortressed heart.

There was a tower at either corner of the inner court, and it was towards the one at the right that we were led. A door with double bolts barred the bottom of the staircase. The governor threw them back, opened the door, and motioned us before him. I heard the regular step of a sentry in the corridor above, and we passed him at the first landing. He paused to glance at us inquiringly, and then continued his round. At the third landing, Maison-Rouge stopped before a heavy iron door, threw back the bolts and pulled it open. Another inner door was revealed, similarly bolted. This he also opened and held back.

“Ah, I am familiar with this room,” said Richelieu, smiling as he passed into it. I started to follow him, but Maison-Rouge motioned me back.

“What! you would separate me from my friend?” cried Richelieu.

“I regret that it is necessary, monsieur,” said the governor; “but it is the rule, as you should know. He shall lodge in the calotte above you.”

As he spoke I fancied I caught a flash of triumph in Richelieu’s eye, but he made no sign.

“Good-by, then, my friend,” he said, and turned away towards the double-barred window. The doors were clanged shut, the bolts thrown, and I was motioned to mount to the floor above. I did so with a heavy heart. With Richelieu I had some hope, but without him I felt hope to be fruitless. Presently we paused before another door, double-bolted like that on the floor below. Behind it, also, there was an inner door. It was opened, I entered, and heard the bolts shot into place. As I looked back at it I saw that in both doors, near the top there was a narrow orifice through which the sentry in the hall could inspect the cells as he passed and hear what was going on in them.
