"It is for that purpose that I came here," replied the new comer, coldly. "I called on Dargental at about eleven o'clock, on the morning of April 9th. He admitted me himself, ushered me into the dining-room, and left me in order to enter his bed-chamber. He returned a moment afterwards with a pistol in his hand; and I had scarcely begun to explain the object of my visit, before he began to abuse me in the most insulting manner. He showered offensive epithets upon me, and uttered the most violent threats against the person whom I wished to place beyond the reach of his knavery. He declared that if she did not pay him the sum of two hundred thousand francs before two days had expired, he would send the letters she had been so imprudent as to write him, to her husband. He added that these letters were then in his pocket, ready to be produced at any moment. Frantic with rage, I sprang at his throat. He freed himself, and threatened me with his pistol; I tried to wrest it from him, but during the struggle, and at a moment when the barrel of the pistol was pointed at his breast, the weapon went off."

"And the bullet pierced Dargental's heart? This was a most unlucky chance. You are remarkably clever. You almost convince me that you were acting only in self-defence, and that the crime you committed was simply justifiable homicide. Well, what after?"

"I lifted the body, placed it in an arm-chair, searched all his pockets, found the note-case he always carried upon his person, opened it, satisfied myself that the letters were there, placed it in my pocket, and left the house without even taking the precaution to wash my blood-stained hands."

"Which left stains upon the lottery tickets you had handled?"

"That is true; I recollect now, that there were some lottery tickets in one of the compartments of the pocket-book."

"Well, you have not told me all. What occurred afterwards?"

"I left the house, fully intending to return home and burn the letters, after showing them to the writer, but, on the Boulevard Haussmann, I saw two men who pretended to be strolling along, looking into the shop windows, but whom I instantly recognised, in spite of their disguise, as two men of a detective agency, whom the lady's husband had hired to watch his wife. Dargental had sent him anonymous letters about her and me. They started after me, and at the corner of the Rue de Rivoli and the Rue des Pyramides one of them stopped to speak to a policeman, while the other continued to follow me. I watched the movements of the policeman out of the corner of my eye, and saw that he refused to interfere. The next one we met might prove less scrupulous, and I might be arrested and taken to the station-house, where I should certainly be searched, and the letters found upon me. I realized my danger, and felt that I had not a moment to lose in getting rid of the letters, so without stopping to reflect, I adopted the first plan that occurred to me. I was just passing one of the outlets of the Place du Carrousel. There was a long line of vehicles. The private detectives were following me at a little distance, talking together, probably making arrangements to pick a quarrel with me, in order to attract the attention of the police, who would take us to the station house. At all events their conversation was so animated that they forgot to watch my movements. In the last cab on the line I saw two gentlemen. The window was open, and I dropped the pocket-book inside, carefully noting the number of the vehicle as I did so. The two detectives gave me no further trouble, however, as no policeman would consent to lend them a helping hand, still they followed me to Montrouge. There is a house there with which I am familiar, and which has two outsets. I entered it, and made my escape by one door, while the two rascals were talking with the porter at the other."

"Is this all you have to tell me?" inquired M. Robergeot.

"Yes, sir," the man replied, coldly. "You now merely have to send me to prison."

"Which I shall proceed to do so as soon as certain formalities are complied with. Your disclosures were so unexpected that I quite forgot to ask your name, profession, age and residence."
