"Chatelain, Chatelain, why not be sensible? Tell me something about Captain de Saint-Avit."

"

I know nothing." He spoke sharply.

"Nothing? Then what were you saying a little while ago?"

"Captain de Saint-Avit is a brave man." He muttered the words with his head still obstinately bent. "He went alone to Bilma, to the Air, quite alone to those places where no one had ever been. He is a brave man."

"He is a brave man, undoubtedly," I answered with great restraint. "But he murdered his companion, Captain Morhange, did he not?"

The old Sergeant trembled.

"He is a brave man," he persisted.

"Chatelain, you are a child. Are you afraid that I am going to repeat what you say to your new Captain?"

I had touched him to the quick. He drew himself up.
