"Does Mademoiselle Stangerson wish to put everybody to sleep, to-night ?" "Perhaps," replied Rouletabille; but I could see he was thinking of something else.
"But what about us ?" I exclaimed.

"How do we know that we have not been drugged ?" "Do you feel indisposed ?" Rouletabille asked me coolly.
"Not in the least." "Do you feel any inclination to go to sleep ?" "None whatever." "Well, then, my friend, smoke this excellent cigar." And he handed me a choice Havana, one Monsieur Darzac had given him, while he lit his briarwood--his eternal briarwood.
We remained in his room until about ten o'clock without a word passing between us.

Buried in an armchair Rouletabille sat and smoked steadily, his brow in thought and a far-away look in his eyes.

On the stroke of ten he took off his boots and signalled to me to do the same.

As we stood in our socks he said, in so low a tone that I guessed, rather than heard, the word: "Revolver." I drew my revolver from my jacket pocket.
"Cock it!" he said.
I did as he directed.
Then moving towards the door of his room, he opened it with infinite precaution; it made no sound.
