McKee rode close under this ledge and stood in his saddle, lips parted and eyes alight. He could hold off a regiment there; what chance would one unsuspecting man have? As he stood so he unstrapped his gun and lay it with its belt on the shelf.

He dropped down and rode into a nearby, narrow crevice, where his horse could remain concealed, dismounted, and took down his rope, preparatory to tieing the animal.

He believed his growing haste was only anticipation, but perhaps there was a quality of premonition there. He had been unable to follow Beck's progress and remain concealed himself; therefore he had not seen the roan pick up his swinging trot as Tom's concentrated thought reached ferment and he sought relief in speed.

McKee reached for the reins to lead his horse further into the crevice. Then his heart leaped and he went quickly cold as he looked at the animal.

The gray's head was up, ears stiff, eyes alert as a horse will pose on sensing the approach of another animal. Even as Sam's hands flashed out for his nose the nostrils fluttered and had he been an instant later a betraying whinner would have gone echoing through the rocks to warn Beck. He drove his fingers into the soft muzzle and choked back the sound. The gray stepped quickly and shook his head whereat McKee relaxed his grasp somewhat. They then stood quiet, both listening, the horse alert, the man weak and white, breathing in fluttering gasps.

He was trapped! Outside on the ledge where he had planned to wait and shoot Beck down without giving or taking a chance, lay his gun. On either side the walls rose sheer, without so much as a hand-hold for yards above his head; before was a blank wall; outside was Tom Beck. And fear of a degree such as the man had never known shook his body.

It was that fear which is as dangerous to an enemy as the most absurd courage. Discovery would mean catastrophe; he had nothing to gain by shirking now!

Slowly he released his grip on the gray's nostrils, holding ready to clamp down again should the horse attempt to greet the other. He heard hoofs clatter on the rock basin, knew that Beck had stopped. Then the wind soughed through the rocks with its prolonged organ tone and for the moment McKee could only guess what happened out there.

The gray, with head turned, stared toward the opening of the crevice and then as no other sounds came, swung his head back to its normal position and switched rather languidly at flies.

Carefully McKee stole toward the entrance of the crevice where he might see the other man. He went with a hand against the granite, putting down his boots very carefully, hoping against hope that Beck would be far enough away so that he might either recover his gun or devise some means of escape. Perspiration ran from beneath his hat band and his hands were clammy cold. His breath continued in that fluttering gasp.
