I was cruelly ashamed of my indifference when I thought about it; but I am now satisfied that it was not so much the result of weakness of character as of causes apart from myself which would have acted in the same way upon any young man placed in my situation. From the first, and when I faced my task of vengeance, an insurmountable obstacle arose before me. It is equally easy and sublime to strike an attitude and exclaim: "I swear that I will never rest until I have punished the guilty one." In reality, one never acts except in detail, and what could I do? I had to proceed in the same way as justice had proceeded, to reopen the inquiry which had been pushed to its extremity without any result.

I began with the Judge of Instruction,* who had had the carriage of the matter, and who was now a Counsellor of the Court. He was a man of fifty, very quiet and plain in his way, and he lived in the Ile de Paris, on the first floor of an ancient house, from whose windows he could see Notre Dame, primitive Paris, and the Seine, which is as narrow as a canal at that place.

* The translator renders literally those terms and phrases relating to the French criminal law and procedure which have no analogous expression in English.

M. Massol, so he was named, was quite willing to resume with me the analysis of the data which had been furnished by the Instruction. No doubt existed either as to the personality of the assassin, or the hour at which the crime was committed. My father had been killed between two and three o'clock in the day, without a struggle, by that tall, broad-shouldered personage whose extraordinary disguise indicated, according to the magistrate, "an amateur." Excess of complication is always an imprudence, for it multiplies the chances of failure. Had the assassin dyed his skin and worn a wig because my father knew him by sight?

To this M. Massol said "No; for M. Cornelis, who was very observant, and who, besides, was on his guard—this is evident from his last words when he left you—would have recognized him by his voice, his glance, and his attitude. A man cannot change his height and his figure, although he may change his face."

M. Massol's theory of this disguise was that the wearer had adopted it in order to gain time to get out of France, should the corpse be discovered on the day of the murder. Supposing that a description of a man with a very brown complexion and a black beard had been telegraphed in every direction, the assassin, having washed off his paint, laid aside his wig and beard, and put on other clothes, might have crossed the frontier without arousing the slightest suspicion. There was reason to believe that the pretended Rochdale lived abroad. He had spoke in English at the hotel, and the people there had taken him for an American; it was therefore presumable either that he was a native of the United States, or that he habitually resided there. The criminal was, then, a foreigner, American or English, or perhaps a Frenchman settled in America. As for the motive of so complicated a crime, it was difficult to admit that it could be robbery alone. "And yet," observed the Judge of Instruction, "we do not know what the note-case carried off by the assassin contained. But," he added, "the hypothesis of robbery seems to me to be utterly routed by the fact that, while Rochdale stripped the dead man of his watch, he left a ring, which was much more valuable, on his finger. From this I conclude that he took the watch merely as a precaution to throw the police off the scent. My supposition is that the man killed M. Cornelis for revenge.

Then the former Judge of Instruction gave me some singular examples of the resentment cherished against medical experts employed in legal cases, Procureurs of the Republic, and Presidents of Assize. His theory was, that in the course of his practice at the bar my father might have excited resentment of a fierce and implacable kind; for he had won many suits of importance, and no doubt had made enemies of those against whom he employed his great powers. Supposing one of those persons, being ruined by the result, had attributed that ruin to my father, there would be an explanation of all the apparatus of this deadly vengeance.

M. Massol begged me to observe that the assassin, whether he were a foreigner or not, was known in Paris. Why, if this were not so, should the man have so carefully avoided being seen in the street? He had been traced out during his first stay in Paris, when he bought the wig and the beard, and that time he put up at a small hotel in the Rue d'Aboukir under the name of Rochdale, and invariably went out in a cab. "Observe also," said the Judge, "that he kept his room on the day before the murder, and on the morning of the actual day. He breakfasted in his apartment, having breakfasted and dined there the day before. But, when he was in London, and when he lived at the hotel to which your father addressed his first letters, he came and went without any precautions."

And this was all. The addresses of three hotels—such were the meagre particulars that formed the whole of the information to which I listened with passionate eagerness; the magistrate had no more to tell me. He had small, twinkling, very light eyes, and his smooth face wore an expression of extreme keenness. His language was measured, his general demeanor was cold, obliging, and mild, he was always closely shaven, and in him one recognized at once the well-balanced and methodical mind which had given him great professional weight. He acknowledged that he had been unable to discover anything, even after a close analysis of the whole existing situation of my father, as well as his past.

"Ah, I have thought a great deal about this said he, adding that before he resigned his post as Judge of Instruction he had carefully reperused the notes of the case. He had again questioned the concierge of the Imperial Hotel and other persons. Since he had become Counsellor to the Court, he had indicated to his successor what he believed to be a clue; a robbery committed by a carefully made-up Englishman had led him to believe the thief to be identical with the pretended Rochdale. Then there was nothing more.
