“Very good,” said she, as she dropped it by her side.

“You feel for your own people and I feel for mine, and so we are equal. But you have said one wise and kindly thing within these walls, Colonel Gerard. You have said, 'One man more or less can make no difference in a struggle between two great armies.' Your lesson of nobility is not wasted. Behind those fagots is an unguarded door. Here is the key to it. Go forth, Colonel Gerard, and I trust that we may never look upon each other's faces again.”

I stood for an instant with the key in my hand and my head in a whirl. Then I handed it back to her.

“I cannot do it,” I said.

“Why not?”

“I have given my parole.”

“To whom?” she asked.

“Why, to you.”

“And I release you from it.”

My heart bounded with joy. Of course, it was true what she said. I had refused to give my parole to Sergine. I owed him no duty. If she relieved me from my promise my honour was clear. I took the key from her hand.
