And then another man cried out, stooped, wrenched the gun from the limp hand of Donnegan and opened the cylinder. He spun it: daylight was glittering through the empty cylinder.

At this the man stiffened, and with a low bow which would have done credit to a drawing-room, he presented the weapon butt first to Lord Nick.

"Here's something the sheriff will want to see," he said, "but maybe you'll be interested, too."

But Lord Nick, with the gun in his hand, stared at it dumbly, turned the empty cylinder. And the full horror crept slowly on his mind. He had not killed his brother, he had murdered him. As his eyes cleared, he caught the glitter of the eyes which surrounded him.

And then Lou Macon was on her knees with her hands clasped at her breast and her face glorious.

"Help!" she was crying. "Help me. He's not dead, but he's dying unless you help me!"

Then Lord Nick cast away his own revolver and the empty gun of Donnegan. They heard him shout: "Garry!" and saw him stride forward.

Instantly men pressed between, hard-jawed men who meant business. It was a cordon he would have to fight his way through: but he dissolved it with a word.

"You fools! He's my brother!"

And then he was on his knees opposite Lou Macon.
