"So you really believe ...?"

"I repeat what I said. Before the snowfall, a single arrival, Mathias, and a single departure, the stranger."

"And Madame de Gorne? Was she too killed and thrown down the well like her husband?"

"No, carried off."

"Carried off?"

"Remember that her bedroom was broken down with a hammer."

"Come, come, sergeant! You yourself declare that there was only one departure, the stranger's."

"Stoop down. Look at the man's footprints. See how they sink into the snow, until they actually touch the ground. Those are the footprints of a man, laden with a heavy burden. The stranger was carrying Madame de Gorne on his shoulder."

"Then there's an outlet this way?"

"Yes, a little door of which Mathias de Gorne always had the key on him. The man must have taken it from him."
