Suddenly St. Pierre came nearer the door, and his voice was more distinct. "Chere-coeur, I tell you it is the greatest joke of my life," he heard him say. "We are safe. If it should come to the worst, we can settle the matter in another way. I can not but sing and laugh, even in the face of it all. And she, in that very innocence which amuses me so, has no suspicion—"

He turned, and vainly David keyed his ears to catch the final words. The voices in the cabin grew lower. Twice he heard the soft laughter of the woman. St. Pierre's voice, when he spoke, was unintelligible.

The thought that his random adventure was bringing him to an important discovery possessed Carrigan. St. Pierre, he believed, had been on the very edge of disclosing something which he would have given a great deal to know. Surely in this cabin there must be a window, and the window would be open—

Quietly he felt his way through the darkness to the shore side of the cabin. A narrow bar of light at least partly confirmed his judgment. There was a window. But it was almost entirely curtained, and it was closed. Had the curtain been drawn two inches lower, the thin stream of light would have been shut entirely out from the night.

Under this window David crouched for several minutes, hoping that in the calm which was succeeding the storm it might be opened. The voices were still more indistinct inside. He scarcely heard St. Pierre, but twice again he heard the low and musical laughter of the woman. She had laughed differently with HIM—and the grim smile settled on his lips as he looked up at the narrow slit of light over his head. He had an overwhelming desire to look in. After all, it was a matter of professional business—and his duty.

He was glad the curtain was drawn so low. From experiments of his own he knew there was small chance of those inside seeing him through the two-inch slit, and he raised himself boldly until his eyes were on a level with the aperture.

Directly in the line of his vision was St. Pierre's wife. She was seated, and her back was toward him, so he could not see her face. She was partly disrobed, and her hair was streaming loose about her. Once, he remembered, she had spoken of fiery lights that came into her hair under certain illumination. He had seen them in the sun, but never as they revealed themselves now in that cabin lamp glow. He scarcely looked at St. Pierre, who was on his feet, looking down upon her—not until St. Pierre reached out and crumpled the smothering mass of glowing tresses in his big hands, and laughed. It was a laugh filled with the unutterable joy of possession. The woman rose to her feet. Up through her hair went her two white, bare arms, encircling St. Pierre's neck. The giant drew her close. Her slim form seemed to melt in his, and their lips met.

And then the woman threw back her head, laughing, so that her glory of hair fell straight down, and she was out of reach of St. Pierre's lips. They turned. Her face fronted the window, and out in the night Carrigan stifled a cry that almost broke from his lips. For a flash he was looking straight into her eyes. Her parted lips seemed smiling at him; her white throat and bosom were bared to him. He dropped down, his heart choking him as he stumbled through the darkness to the edge of the raft. There, with the lap of the water at his feet, he paused. It was hard for him to get Breath. He stared through the gloom in the direction of the bateau. Marie-Anne Boulain, the woman he loved, was there! In her little cabin, alone, on the bateau, was St. Pierre's wife, her heart crushed.

And in this cabin on the raft, forgetful of her degradation and her grief, was the vilest wretch he had ever known—St. Pierre Boulain. And with him, giving herself into his arms, caressing him with her lips and hair, was the sister of the man he had helped to hang—CARMIN FANCHET!
