His manner was curt and plainly showed that he was not pleased with the latest addition to the party. But Kenneth Gregory cared little for that. If the Gray Ghost was at the goose-neck, the chances were that Mascola would be in the cave. And Mascola must be given no chance to escape.

As he followed after the others down the winding sheep-trail, before Gregory's eyes flashed a vision of his father's battered face staring up at him from the canvas bundle on the hatch. Then came the memory of Mascola's insolent look of triumph when he had first beheld Richard Gregory's son on the wharf at Legonia. Why had he not seen and understood before this?

But then, he had had no proof. He reflected bitterly that he had no proof now. Only a Mexican's unsupported word that Mascola had stood by while his father and Bill Lang were murdered by his men.

That was not enough. Mascola might be convicted of smuggling but he would go clear on the charge of murder.

Gregory shook his head slowly in the darkness. No, Mascola would not go clear. He would choke a confession from the Italian with his own hands. Somewhere below him in the fog, a girl waited for him to bring back her father's murderer. The girl he loved, had always loved, but had never known it before to-night. If he failed, he could never face Dickie Lang again. But he would not fail.

His thoughts were interrupted by the sound of sharp scuffling ahead. Rushing down the trail he came upon the deputies struggling with two men in the bottom of a small ravine. As he assisted the revenue men in securing their captives, he heard Smith whisper: "Down the gulch, men. Take it easy. It's steep. Stay with these fellows, Joe."

The air which sucked through the ravine grew colder as they descended. Then the dank atmosphere became strongly permeated with the odor of fish. Gregory felt a hand upon his arm.

"Go last," Smith ordered. "Watch the others. Do what they do. No more."

Foot by foot, the men wormed their way over the dry sticks which choked the entrance to the cave. Then Smith ordered a halt.

Leaving a half dozen men at the entrance he instructed them: "Watch this outlet. When you hear a shot inside, light the signal flares and throw them
