"In that you are agreeably distinguished from me," was his reply, made in a tone of utter indifference, "for I wasted my morning in putting my correspondence in order."

"Yes," I continued, "very interesting. I passed two hours with M. Massol."

I had reckoned a good deal on the effect of this name, which must have instantly recalled the inquiry into the mystery of the Imperial Hotel to his memory. The muscles of his face did not move. He laid down the tongs, leaned back in his chair, and said in an absent manner:

"The former Judge of Instruction? What is he doing now?"

Was it possible that he really did not know where the man, whom, if he were guilty, he ought to have dreaded most of all men, was then living? How was I to know whether this indifference was feigned? The trap I had set appeared to me all at once a childish notion. Admitting that my stepfather's pulses were even now throbbing with fever, and that he was saying to himself with dread: "What is he coming to? What does he mean?" why, this was a reason why he should conceal his emotion all the more carefully. No matter. I had begun; I was bound to go on, and to hit hard—or cease to hit at all.

"M. Massol is Counsellor to the Court," I replied, and I added—although this was not true—"I see him often. We were talking this morning of criminals who have escaped punishment. Only fancy his being convinced that Troppmann had an accomplice. He founds his belief on the details of the crime, which presupposes two men, he says. If this be true it must be admitted that 'Messieurs The Assassins' have a kind of honour of their own, however odd that may appear, since the child-killing monster let his own head be cut off without denouncing the other. Nevertheless, the accomplice must have had some bad times before him, after the discovery of the bodies and the arrest of his comrade. I, for my part, would not trust to that honour, and if the humour took me to commit a crime, I should do it by myself. Would you?" I asked jestingly.

These two little words meant nothing, were merely an insignificant jest, if the man to whom I put my odd question was innocent. But, if he were guilty, those two little words were enough to freeze the marrow in his bones. He surrounded himself with smoke while listening to me, his eyelids half veiled his eyes; I could no longer see his left hand, which hung over the far side of his chair, and he had put the right into the pocket of his morning-coat. There was a short pause before he answered me—very short—but the interval, perhaps a minute, that divided his reply from my question was a burning one for me. But what of this? It was not his way to speak in a hurry; and besides, my question had nothing interesting in it if he were not guilty, and if he were, would he not have to calculate the bearing of the phrase which he was about to utter with the quickness of thought? He closed his eyes completely—his constant habit—and said, in the unconcerned tone of a man who is talking generalities:

"It is a fact that scraps of conscience do remain intact in very depraved individuals. One sees instances of this especially in countries where habits and morals are more genuine and true to nature than ours. There's Spain, for instance, the country that interests you so much; when I lived in Spain, it was still infested by brigands. One had to make treaties with them in order to cross the Sierras in safety; there was no case known in which they broke the contract. The history of celebrated criminal cases swarms with scoundrels who have been excellent friends, devoted sons, and constant lovers. But I am of your opinion, and I think it is best not to count too much upon them."

He smiled as he uttered the last words, and now he looked full at me with those light blue eyes which were so mysterious and impassible. No, I was not of a stature to cope with him, to read his heart by force. It needed capacity of another kind than mine to play in the case of this personage the part of the magnate of police who magnetises a criminal. And yet, why did my suspicions gather force as I felt the masked, dissimulating, guarded nature of the man in all its strength? Are there not natures so constituted that they shut themselves up without cause, just as others reveal themselves; are there not souls that love darkness as others love daylight? Courage, then, let me strike again.

"M. Massol and I," I resumed, "have been talking about what kind of life Troppmann's accomplice must be leading, and also Rochdale's, for neither of us has relinquished the intention of finding him. Before M. Massol's retirement he took the precaution to bar the limitation by a formal notice, and we have several years before us in which to search for the man. Do these criminals sleep in peace? Are they punished by remorse, or by the apprehension of danger, even in their momentary security? It would be strange if they were both at this moment good, quiet citizens, smoking their cigars like you and me, loved and loving. Do you believe in remorse?"
