"Indeed, madame, and you may well think it strange, for have I not seen you drop your fan in order to deceive the man who picks it up?" With that I got to my feet and laid the fan on the table.

She flushed very red, and exclaimed hurriedly:

"All that can be explained."

"No doubt! no doubt!" I replied. "I have never doubted the subtlety of madame's invention."

She drew herself up with great pride, and bowed to me.

I walked to the door. As I opened it, I turned to take one last look at the face which I had so worshipped. It was very white; even the lips were bloodless, and oddly enough I noticed that she wore a loose white gown as on the occasion of our first meeting.

"Adieu," I said, and stepped behind the door.

From the other side of it her voice came to me quietly:

"Does this prove the sword to be lath or steel?"

I shut the door, and went slowly down the stairs, slowly and yet more slowly. For her last question drummed at my heart.
