Rh mystery? No doubt for the purpose of facilitating the inquiries of the agents of the Sûreté? He imagines, perhaps, that the owner of this instrument of crime, the most terrible invented, is going to be found amongst those who are well-known in the slums of Paris who use it. But who can ever say what passes through the brain of an examining magistrate?" Rouletabille added with contemptuous irony.

"Has a mutton-bone been found in The Yellow Room?" I asked him.

"Yes, Monsieur," said Robert Darzac, "at the foot of the bed; but I beg of you not to say anything about it." (I made a gesture of assent.) "It was an enormous mutton-bone, the top of which, or rather the joint, was still red with the blood of the frightful wound. It was an old bone, which may, according to appearances, have served in other crimes. That's what Monsieur de Marquet thinks. He has had it sent to the municipal laboratory at Paris to be analysed. In fact, he thinks he has detected on it, not only the blood of the last victim, but other stains of dried blood, evidences of previous crimes."

"A mutton-bone in the hand of a skilled assassin is a frightful weapon," said Rouletabille, "a more certain weapon than a heavy hammer."

"The scoundrel has proved it to be so," said Monsieur Robert Darzac, sadly. "The joint of the bone found exactly fits the wound inflicted. My belief is that the wound would have been mortal, if the murderer's blow had not been arrested in the act by Mademoiselle Stangerson's revolver.
