“Yes,” observed Mme. Darzac. “Yes, M. Sainclair, it is the same mode of procedure.” And she unfastened her husband’s collar to show the wounds hidden beneath it.
“See!” she said. “They are the same nail prints. I know them well.”
There was a sorrowful silence.
M. Darzac, caring only to solve this strange problem, reviewed the crime of the Glandier. And he repeated what he had said in the Yellow Room:
“There must be a passage in the floor, in the ceiling or in the walls.”
“There is not,” replied Rouletabille.
“Then he must have found some way to make one,” persisted M. Darzac.
“Why?” asked Rouletabille. “Did he do anything of the sort in the Yellow Room?”
“Oh, this isn’t the same thing at all!” I exclaimed. “This apartment is more firmly closed than the Yellow Room since no one could have gotten into it before nor after.”
“No, it is not the same thing,” pronounced Rouletabille. “It is just the opposite. In the Yellow Room, there was a body missing: in the room in the Round Tower, there is a body too many.”
