THE MYSTERY OF THE YELLOW ROOM
of the black foot-marks corresponding with that of Daddy Jacques's boots, which I had established without his suspecting it, on the floor of The Yellow Room. All which was a proof, in my eyes, that the murderer had sought to turn suspicion on to the old servant. Up to that point, Larsan and I are in accord; but no further. It is going to be a terrible matter; for I tell you he is working on wrong lines, and I—I, must fight him with nothing!"
I was surprised at the profoundly grave accent with which my young friend pronounced the last words.
He repeated:
"Yes terrible!—terrible!—terrible! For it is fighting with nothing, when you have only an idea to fight with."
At that moment we passed by the back of the château. Night had come. A window on the first floor was partly open. A feeble light came from it as well as some sounds which drew our attention. We approached until we had reached the side of a door that was situated just under the window. Rouletabille, in a low tone, made me understand, that this was the window of Mademoiselle Stangerson's chamber. The sounds which had attracted our attention ceased, then were renewed for a moment, and then we heard stifled sobs. We were only able to catch these words, which reached us distinctly: "My poor Robert!"—Rouletabille whispered in my ear:—
"If we only knew what was being said in that chamber, my inquiry would soon be finished."
