Jim Horton stood for a moment listening to the sounds of the retreating fiacre as it rattled away over the cobblestones and then turned slowly back, his anger at his discoveries, long repressed by the necessities of his masquerade, suddenly bursting the barriers of his self-control. Moira—innocent—the catspaw, the stool-pigeon for these two rascals! How much did she know? How could Quinlevin have carried the deception out all these years without de Vautrin suspecting something? And if, as it seemed, he was suspicious of them now, who had told? His own duty seemed very clear. Every impulse of honor and decency urged that he find this Duc de Vautrin and tell the whole truth. But there was Moira ... his first duty was to her. But telling her meant revealing the secret of Harry's disgrace and his own part in it. That would be a difficult thing to do, but he would have to do it. He would tell her to-morrow.

As for Harry—he would make short work of him. He went with long determined strides to the appointed spot and Harry met him with a threatening air.

"What the Hell has she been saying?" he muttered.

Jim Horton was angry, but he kept himself well in hand, aware of his own physical superiority to this blustering shell of intrigue, deceit and cowardice, built in his own image. If earlier in the evening he had had his moments of pity for his brother's misfortunes, if he had planned to make restitution for the imprudence that had resulted in their undoing, he had no such gentle feeling or purpose now.

As he didn't reply, his brother continued angrily. "You've gone about your limit, I tell you. What did she tell you?"

"Everything. I've got the whole story. And I'd like to tell you before we go any further that you're just about the crookedest——" He broke off with a shrug.

"What's the use? The worst thing I could say would be a compliment. But you've come to the end of your tether. I don't know why I hoped there might be a chance of getting you to go straight—for her—but I did. The interesting revelations of this charming lady have removed the impression. The money you took from the estate, your questionable deals in America, your habits, put you outside the pale of decency, but the blackmail of the Duc with your own wife as stool-pigeon——"

Harry in a sudden blind fury that took no thought of consequences struck viciously, but Jim, who had been watching for the blow, warded it, tripped his brother neatly and sent him spinning against the wall where he fell and lay motionless. But he was unhurt—only bewildered by the result of his own incapacity.

"Get up!" Jim ordered. "Somebody will be coming along in a moment and we'll both be going with the police."

Harry saw reason in that and slowly got to his feet, pale, still trembling with rage, rubbing his hip joint, but subdued. The place they had chosen was in the shadow and the hour was late, and no one was about, but Jim Horton took a glance up and down the deserted street before he resumed his interrupted remarks.
