I had reached the second floor. At one corner of the long corridor there was a notification that the numbers ran from 300 to 360. A waiter passed me, whistling; two girls were chattering and laughing in a kind of office at the stair-head; the various noises of the courtyard came up through the open windows.  
The moment was opportune for the execution of my project. With these people about the man could not hope to escape from the house. 345, 350, 351, 353—I stood before the door of Edmond Termonde's room; the key was in the lock; chance had served my purpose better than I had ventured to hope. This trifling particular bore witness to the security in which the man whom I was about to surprise was living. Was he even aware that I existed?
 
I paused a moment before the closed door. I wore a short coat, so as to have my revolver within easy reach in the pocket, and I put my right hand upon it, opened the door with my left, and entered without knocking.
 
"Who is there?" said a man who was lying rather than sitting in an arm-chair, with his feet on a table; he was reading a newspaper and smoking, and his back was turned to the door. He did not trouble himself to rise and see whose hand had opened the door, thinking, no doubt, that a servant had come in; he merely turned his head slightly, and I did not give him time to look completely round.
 
"M. Rochdale?" I asked.
 
He started to his feet, pushed away the chair, and rushed to the other side of the table, staring at me with a terrified countenance; his light blue eyes were unnaturally distended, his face was livid, his mouth was half open, his legs bent under him. His tall, robust frame had sustained one of those shocks of excessive terror which almost paralyze the forces of life. He uttered but one word—"Cornelis!"
 
At last I held in my victorious hand the proof that I had been seeking for months, and in that moment I was master of all the resources of my being. Yes, I was as calm, as clear of purpose, as my adversary was the reverse. He was not accustomed to live, like his accomplice, in the daily habits of studied dissimulation. The name, "Rochdale," the terrifying likeness, the unlooked-for arrival! I had not been mistaken in my calculation. With the amazing rapidity of thought that accompanies action I perceived the necessity of following up this first shock of moral terror by a shock of physical terror. Otherwise, the man would hurl himself upon me, in the moment of reaction, thrust me aside and rush away like a madman, at the risk of being stopped on the stairs by the servants, and then? But I had already taken out my revolver, and I now covered the wretch with it, calling him by his real name, to prove that I knew all about him.
 
"M. Edmond Termonde," I said, "if you make one step towards me, I will kill you, like the assassin that you are, as you killed my father."
 
Pointing to a chair at the corner of the half-open window, I added:
 
"Sit down!"
 
He obeyed mechanically. At that instant I exercised absolute control over him; but I felt sure this would cease so soon as he recovered his presence of mind. But even though the rest of the interview were now to go against me, that could not alter the certainty which I had acquired. I had wanted to know whether Edmond Termonde was the man who had called himself Rochdale, and I had secured undeniable proof of the fact. Nevertheless, it was due to myself that I should extract from my enemy the proof of the truth of all my conjectures, that proof which would place my stepfather at my mercy. This was a fresh phase of the struggle.
 
I glanced round the room in which I was shut up with the assassin. On the bed, placed on my left, lay a loaded cane, a hat and an overcoat; on a small table were a steel "knuckle-duster" and a revolver. Among the articles laid out on a chest of drawers on my right a bowie-knife was conspicuous, a valise was placed against an unused door, a wardrobe with a looking-glass stood before another unused door, then came the toilet-stand, and the man, crouching under the aim of my revolver, between the table and the window. He could neither escape, nor reach to any means of defense without a personal struggle with me; but he would have to stand my fire first, and besides, if he was tall and robust, I was neither short or feeble. I was twenty-five, he was fifty. All the moral forces were for me, I must win.
 
"Now," said I, as I took a seat, but without releasing him from the covering barrel of my pistol, "let us talk."
 
"What do you want of me?" he asked roughly. His voice was both hoarse and muffled; the blood had gone back into his cheeks, his eyes, those eyes so exactly like his brother's, sparkled. The brute-nature was reviving in him after having sustained a fearful shock, as though astonished that it still lived.
 
"Come, then," he added, clenching his fists, "I am caught. Fire on me, and let this end."
 
Then, as I made him no answer, but continued to threaten him with my pistol, he exclaimed:
 
"Ah! I understand; it is that blackguard Jacques who has sold me to you in order to get rid of me himself. There's the statute of limitations—he thinks he is safe! But has he told you that he was in it himself, good, honest man, and that I have the proof of this? Ah! he thinks I am going to let you kill me, like that, without speaking? No, I shall call out, we shall be arrested, and all will be known."
 
Fury had seized upon him; he was about to shout "Help!" and the worst of it was that rage was rising in me also. It was he, with that same hand which I saw creeping along the table, strong, hairy, seeking something to throw at me—yes—it was he who had killed my father.
 
One impulse more of anger and I was lost; a bullet was lodged in his body, and I saw his blood flow. Oh, what good it would have done me to see that sight!
 
But no, I soon made the sacrifice of this particular vengeance. In a second, I beheld myself arrested, obliged to explain everything, and my mother exposed to all the misery of it.
 
Happily for me, he also had an interval of reflection. The first idea that must have occurred to him was that his brother had betrayed him, by telling me one-half of the truth, so as to deliver him up to my vengeance. The second, no doubt, was that, for a son who came to avenge his dead father, I was making a good deal of delay about it. There was a momentary silence between us. This allowed me to regain my coolness, and to say: "You are mistaken," so quietly that his amazement was visible in his face. He looked at me, then closed his eyes, and knitted his brow. I felt that he could not endure my resemblance to my father.
 
"Yes, you are mistaken," I continued deliberately, giving the tone of a business conversation to this terrible interview. "I have not come here either to have you arrested or to kill you. Unless," I added, "you oblige me to do so yourself, as I feared just now you would oblige me. I have come to propose a bargain to you, but it is on the condition that you listen, as I shall speak, with coolness."
 
Once more we were both silent. In the corridor, almost at the door of the room, there were sounds of feet, voices, and peals of laughter. This was enough to recall me to the necessity of controlling myself, and him to the consciousness that he was playing a dangerous game. A shot, a cry, and someone would enter the room, for it opened upon the corridor. Edmond Termonde had heard me with extreme attention; a gleam of hope, succeeded by a singular look of suspicion, had passed over his face.
 
"Make your conditions," said he.
 
"If I had intended to kill you," I resumed, so as to convince him of my sincerity by the evidence of his senses, "you would be dead already." I raised the revolver. "If I had intended to have you arrested, I would not have taken the trouble to come here myself; two policemen would have been sufficient, for you don't forget that you are a deserter, and still amenable to the law."
 
"True," he replied simply, and then added, following out a mental argument which was of vital importance to the issue of our interview:
 
"If it is not Jacques, then who is it that has sold me?"
 
"I held you at my disposal," I continued, without noticing what he had said, "and I have not availed myself of that. Therefore I had a strong reason for sparing you yesterday, ere yesterday, this morning, a little while ago, at the present moment; and it depends upon yourself whether I spare you altogether."
 
"And you want me to believe you," he answered, pointing to my revolver which I still continued to hold in my hand, but no longer covering him with it. "No, no," and he added, with an expression which smacked of the barrack-room, "I don't tumble to that sort of thing."
 
"Listen to me," said I, now assuming a tone of extreme contempt. "The powerful motive which I have for not shooting you like a mad dog, you shall learn. I do not choose that my mother should ever know what a man she married in your brother. Do you now understand why I resolved to let you go? Provided you are of the same mind, however; for even the idea of my mother would not stop me, if you pushed me too far. I will add, for your guidance, that the limitation by which you supposed yourself to be safe from pursuit for the murder in 1864 has been traversed; you are therefore staking your head at this moment. For ten years past you have been successfully levying blackmail on your brother. I do not suppose you have merely played upon the chord of fraternal love. When you came from America to assume the personality of Rochdale, it was clearly necessary that he should send you some instructions. You have kept those letters. I offer you one hundred thousand francs for them."
 
"Sir," he replied slowly, and his tone showed me that for the moment he had recovered his self-control, "how can you imagine that I should take such a proposal seriously? Admitting that any such letters were ever written, and that I had kept them, why should I give up a document of this kind to you? What security should I have that you would not have me laid by the heels the moment after! Ah!" he cried, looking me straight in the face, "you know nothing! That name! That likeness! Idiot that I am, you have tricked me."
 
His face turned crimson with rage, and he uttered an oath.
 
"You shall pay for this!" he cried; and at the same instant, when he was no longer covered by my pistol, he pushed the table upon me so violently, that if I had not sprung backwards I must have been thrown down; but he already had time to fling himself upon me and seize me round the body. Happily for me the violence of the attack had knocked the pistol out of my hands, so that I could not be tempted to use it, and a struggle began between us in which not one word was spoken by either.
 
With his first rush he had flung me to the ground; but I was strong, and the strange premonitions of danger, from which I suffered in my youth, had led me to develop all my physical energy and adroitness.
 
I felt his breath on my face, his skin upon my skin, his muscles striving against mine, and at the same time the dread that our conflict might be overheard gave me the coolness which he had lost. After a few minutes of this tussle, and just as his strength was failing, he fastened his teeth in my shoulder so savagely that the pain of the bite maddened me. I wrenched one of my arms from his grasp and seized him by the throat at the risk of choking him. I held him under me now, and I struck his bead against the floor as though I meant to smash it. He remained motionless for a minute, and I thought I had killed him. I first picked up my pistol, which had rolled away to the door, and then bathed his forehead with water in order to revive him.
 
When I caught sight of myself in the glass, with my coat-collar torn, my face bruised, my cravat in rags, I shuddered as if I had seen the specter of another Andre Cornelis. The ignoble nature of this adventure filled me with disgust; but it was not a question of fine-gentleman fastidiousness. My enemy was coming to himself, I must end this. I knew in my conscience I had done all that was possible to fulfill my vow in regard to my mother. The blame must fall upon destiny. the wretch had half-raised himself, and was looking at me; I bent over him, and put the barrel of my revolver within a hair's breadth of his temple.
 
"There is still time," I said. "I give you five minutes to decide upon the bargain which I proposed to you just now; the letters, and one hundred thousand francs, with your liberty; if not, a bullet in your head. Choose. I wished to spare you on account of my mother; but I will not lose my vengeance both ways. I shall be arrested, your papers will be searched, the letters will be found, it will be known that I had a right to shoot you. My mother will go mad with grief; but I shall be avenged. I have spoken. You have five minutes, not one more."
 
No doubt my face expressed invincible resolution. The assassin looked at that face, then at the clock. He tried to make a movement, but saw that my finger was about to press the trigger.
 
"I yield," he said.
 
I ordered him to rise, and he obeyed me.
 
"Where are the letters?"
 
"When you have them," he implored, with the terror of a trapped beast in his abject face, "you will let me go away?"
 
"I swear it," I answered; and, as I saw doubt and dread in his quaili............
