"Capitaine Rotherby," he said, "my friend and I represent a little group of people who have some interest in the place where we met last night. We are deputed to ask you to explain, if you can, your conduct,—your attack, which it seemed to us was absolutely unprovoked, upon an habitué of the place and an associate of our own."
"There is only one explanation which I can make," I answered slowly. "I went there, as Louis will tell you, absolutely a stranger, and absolutely by chance. Chance decreed that I should meet face to face the one man in the world against whom I bear a grudge, the one man whom I had sworn to punish whenever and wherever I might meet him."
Monsieur Decresson bowed.
"There are situations," he admitted, "which can only be dealt with in that manner. Do not think me personal or inquisitive, I beg of you, but—I ask in your own interests—what had you against this man Tapilow?"
"Monsieur Decresson," I said, "I will answer you frankly. The man whom I punished last night, I punished because I have proved him to be guilty of conduct unbecoming to a gentleman. I punished him because he broke the one social law which in my country, at any rate, may not be transgressed with impunity."
"What you are saying now," Monsieur Grisson interrupted, "amounts to an accusation. Tapilow is known to us. These things must be spoken of seriously. You speak upon your honor as an English soldier and a gentleman?"
"Messieurs," I answered, turning to both of them, "it is agreed. I speak to you as I would speak to the judge before whom I should stand if I had murdered this man, and I tell you both, upon my honor, that the treatment which he received from me he merited. He borrowed my money and my brother's money. He accepted the hospitality of my brother's house, the friendship of his friends. In return, he robbed him of the woman whom he loved."
"The quarrel," Monsieur Decresson said softly, "seems, then, to have been another's."
"Messieurs," I answered, "my brother is an invalid for life. The quarrel, therefore, was mine."
Decresson and his companion exchanged glances. I leaned back in my chair. The three of them talked together earnestly for several minutes in an undertone. Then Louis, with a little sigh of relief, rose to his feet and came over to my side.
