"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."
