At last they slid down into the depths of the dark lake, to lie forever there in that embrace. And still the cataracts played on, sounding their loud, triumphant, never-ending tune.

I was running down the tunnel again. I was running to Jacqueline, but something diverted me. It was the face of Lacroix, peering at me from among the crevices of the rocks with the same evil smile. I knew from the look on it that he had seen all and had been infinitely pleased thereby.

I caught at him; I wanted to get my hands on him and strangle him, too, and fling him down, and stamp his features out of human semblance. But he eluded me and darted back into the cliff.

I followed him hard. This time I did not mean to let him go.

Lacroix was running toward the gold-mine. He made no effort to dodge into any of the unknown recesses of the caves, but ran at full speed across the open space and plunged into the tunnel leading to the shore by the château.

I caught him near the entrance and held him fast.

He struggled in my grasp and screamed.

"Go back! For the love of God, go back, monsieur!" he shrieked. "Let me go! Let me go!"

He fought so desperately that he slipped out of my hands and darted into the mine again, taking the tunnel which led toward the Old Angel, and thence wound back toward the château.

I caught him again before the cave where Jacqueline lay. I wound my arms around him. A dreadful suspicion was creeping into my mind.
