“By Jove!” exclaimed Cameron. “Isn't that great?”

“Very fine, indeed,” said the Inspector softly. Both men's guns were lined upon the conspirators.

Then the half-breed spoke, shrugging his shoulders in contempt.

“Let heem go. Bah! No good.” He spat upon the ground.

Raven stood as he was for a few moments, smiling.

“Good-bye, all,” he said. “Bon jour, Louis. Let no man move! Let no man move! I never need to shoot at a man twice. Little Thunder knows. And don't follow!” he added. “I shall be waiting behind the rocks.”

He slowly backed away from the group, turned in behind a sheltering rock, then swiftly began to climb the rocky sides of the canyon. The moment he was out of sight Little Thunder dodged in behind the ledges, found his rifle, and, making a wide detour, began to climb the side of the ravine at an angle which would cut off Raven's retreat. All this took place in full view of the two watchers above.

“Let's get that devil,” said the Inspector. But Cameron was already gone. Swiftly along the lip of the canyon Cameron ran and worked his way down the side till he stood just over the sloping ledge upon which the Indian was crouched and waiting. Along this lodge came the unconscious Raven, softly whistling to himself his favourite air,

“Three cheers for the red, white and blue.”

There was no way of warning him. Three steps more and he would be within range. The Inspector raised his gun and drew a bead upon the crouching Indian.
