Then, after an apparent decision, he added: "Daddy Jacques was with Monsieur Stangerson in the laboratory--and it was lucky for him he was." "Then what part did his revolver play in the tragedy ?--It seems very clear that this weapon did less harm to Mademoiselle Stangerson than it did to the murderer." The magistrate made no reply to this question, which doubtless embarrassed him.

"Monsieur Stangerson," he said, "tells us that the two bullets have been found in The Yellow Room, one embedded in the wall stained with the impression of a red hand--a man's large hand--and the other in the ceiling." "Oh! oh! in the ceiling!" muttered Rouletabille.

"Not a bit of it!" he said, "more entangled than ever! It's true, I have an idea--" "What's that ?" I asked.
"I can't tell you what it is just at present--it's an idea involving the life or death of two persons at least." "Do you think there were accomplices ?" "I don't think it--" We fell into silence.

Presently he went on: "It was a bit of luck, our falling in with that examining magistrate and his Registrar, eh?
What did I tell you about that revolver ?" His head was bent down, he had his hands in his pockets, and he was whistling.
After a while I heard him murmur: "Poor woman!" "Is it Mademoiselle Stangerson you are pitying ?" "Yes; she's a noble woman and worthy of being pitied!--a woman of a great, a very great character--I imagine--I imagine." "You know her then ?" "Not at all.
