With a plea to him to be careful—behind which all her agony of apprehension was repressed and mastered—Kate wheeled her horse and galloped back.

Laramie, skirting a depression, rode into a break leading to the creek bed. The creek was practically dry; just a thread of water here and there among the rocks marked the course of flood time. Dismounting, Laramie shook himself out of the saddle and laying his rifle across his arm, walked carefully down-stream along the bed of the creek.

He knew if he were seen first, the fight would be over before he got into it; of chances to kill from cover, the criminal he felt sure he was hunting, would need but one. No man from the Falling Wall country was Stone's superior in the craft of hiding; but none was Laramie's equal in the art of surprise; and Laramie meant, for once, to make an antagonist formidable from cover, show in the open.

With this alone in purpose, he stalked with the patience of an Indian from point to point and cover to cover down toward the bridge; crouching, halting and peering; slipping from the shoulder of a rock to the shelter of a boulder; flattening on his stomach to worm his way under a projecting ledge and sliding noiselessly on his back down the face of a water-worn glacis—but drawing closer all the time to the bridge.

He knew every inch of the ground. He knew how well his quarry had concealed himself to render surprise impossible. But Stone's very safety in this respect made his retreat more difficult. A man lying in wait under the Double-draw, staked practically everything on one chance: that the man he sought to kill should cross the bridge. It were then easy to pick him off from behind. But if the intended victim, suspicious, should get unseen into the creek bed, the skulker could hardly avoid a fight.

Three hundred yards above the bridge, the creek walls open in an ellipse, narrowing abruptly where the bridge spans them. This open space has been scoured by floods until the bedrock lies like a polished floor and it was now dry except where the piers of the bridge stood in stagnant pools. Once within this amphitheater whose vertical walls rise twenty to thirty feet, no fighting cover is available.

Behind a rocky point that guarded the upper entrance of the opening, stood Laramie. He was watching the shadow cast by a shrub that sprang, shallow-rooted, from a crevice in the bedrock. For an interminable time he waited, only noting the slow swing of the narrow shadow as the morning sun, flooding the rock-basin, rose in majestic course. Gradually the deflection of the slender indicator, moving like a finger on the rock dial, marked the turn of the sun well past the shoulder of the point at which Laramie must emerge. When that moment came he looked sharply out, sprang from behind the point and ran sidewise into the narrow shadow thrown from the curving wall.

Stone, uneasy and alert, stood under the bridge, his rifle across his arm. The two men saw each other almost at the same instant. For Stone, it was the climax of a hatred long nursed because of a supremacy long challenged. And for him it was an open field with weapons in which his skill was as matchless as Laramie's was held to be, at close quarters, with a Colt's revolver.

Nor had Laramie underestimated the chances of an encounter under such circumstances. He counted only on the slight advantage of a surprise—knowing from disagreeable experiences how a surprise jars the poise; and there persisted in his mind, what he had never until then hinted to another, that Stone, shooting as an assassin from cover and Stone himself facing death, might shoot differently. On these slender hopes he covered Stone, as the ex-rustler jumped his rifle to his check, and cried to him to pitch up.

Stone's answer was a bullet. His shot echoed Laramie's, and as Laramie whipped the hat from his enemy's head, his bullet tore through the right side of Laramie's belt. Bare-headed, and thirsty to close on his antagonist, Stone, jumping from Laramie's second bullet, ran forward, hugging the creek wall, dropped on one knee, fired, and ran in again. Laramie refused to be tempted from the shadow in which he stood, until Stone, rounding the wall again as he came on, firing, threatened to find partial cover should Laramie stand still. It was a contest of deadly fencing, of steady heads and cool wit, a struggle in instant strategy. And if Stone meant to force Laramie into the sunshine, he now succeeded—but at a fearful cost. Laramie jumped not only into the sunshine but into the blinding sun itself, and when Stone ran in again, Laramie tore open his hip with a bullet. It knocked the foreman over as if it had been a mallet. But he was swiftly up and firing persistently almost outlined with bullets Laramie's figure against the rock wall. He splintered the grip of Laramie's revolver in its holster, he cut the sleeve from his wrist, and tore hair from the right side of his head; but he could not stop him. Enraged, and realizing too late how every possibility in the fight had been figured out by his enemy before he stepped into sight, Stone, crippled, yet forced to circle, dropped once more on his knee to smash in a final shot.
