"The position in which you were captured leaves no doubt."

"None at all; only, I will venture to ask you this: what sort of wound did Altenheim die of?"

"Of a wound in the throat caused by a knife."

"And where is the knife?"

"It has not been found."

"How could it not have been found, if I had been the assassin, considering that I was captured beside the very man whom I am supposed to have killed?"

"Who killed him, according to you?"

"The same man that killed Mr. Kesselbach, Chapman, and Beudot. The nature of the wound is a sufficient proof."

"How did he get away?"

"Through a trap-door, which you will discover in the room where the tragedy took place."
