Several times he thought Margot was going to give out, but a few words from him inspired her with a new courage. In the last of these pauses he listened acutely. The silence was absolute. They must be safe by now. They had been climbing for nearly an hour. He urged her to make one more effort, but she was unequal to it and entirely collapsed.

Lifting her in his arms he carried her to where a huge overhanging boulder formed a shallow shelter and laid her down. Resting her head on his knee, he covered her with his coat. Then with his back to the rock he waited for the daylight.

With the first brightening of the dove-grey sky he saw that they had climbed further than he had reckoned. They were on the slope beneath the Tete-du-Chien; above them towered the great bluff, its beetling front steel grey, stained with cinnamon, and around them, as if the greater gods had pelted it in sport, huge boulders heaped in fantastic confusion. Below them the olive groves were saturnine; the roofs of the Condamine a sullen crimson, and the sea’s immense tranquillity painted with a pale fire.

They rose stiffly, their faces haggard in the dawn. Slowly and painfully they descended the mountain.

“What happened,” he asked, “that night?...”

“I don’t know. I never understood. It was very late; I heard a noise in the professor’s room and tried his door; it opened. All was dark. There was a curious smell. Again I heard a noise. I was afraid he was ill. I hurried to his assistance. Some one caught me from behind, and a hand covered my mouth. I struggled, but I had no power. They bound and gagged me. Just as we were going away one of them flashed an electric torch on the floor. I saw the professor lying face downward. It was horrible....”

“Yes, I know. They killed the poor old man. But what after that?”
