“Pat!” he whispered.

Then he knew; saw it all as clearly as though he had witnessed it—­the ambushment in the blinding sandstorm; the terror-stricken Waco; the frightened ponies; the lunging and swaying buckboard.  And Pat, left for dead, but who had dragged himself from the roadway in dumb agony.

The dole of light from the sinking sun was gone.  Waring’s hands came away from the opened shirt shudderingly.  He wiped his hands on the sand, and, rising, ran back to Dex.  He returned with a whiskey flask.  Pat was of tough fiber and tremendous vitality.  If the spark were still unquenched, if it could be called back even for a breath, that which Waring knew, yet wanted to confirm beyond all doubt, might be given in a word.  He raised Pat’s head, and barely tilted the flask.  The spirit of the mortally stricken man, perchance loath to leave such a brave hermitage, winged slowly back from the far shore of dreams.  In the black pit of the arroyo, where death crouched, waiting, life flamed for an instant.

Waring felt the limp body stir.  He took Pat’s big, bony hand in his.

“Pat!” he whispered.

A word breathed heavily from the motionless lips.  “You, Jim?”

“Yes!  For God’s sake, Pat, who did this thing?”

“Brewster—­Bob.  Letter—­in my coat.”

“I’ll get him!” said Waring.

“Shake!” exclaimed the dying man, and the grip of his hand was like iron.  Waring thought he had gone, and leaned closer.  “I’m—­kind of tired—­Jim.  Reckon—­I’ll—­rest.”

Waring felt the other’s grip relax.  He drew his hand from the stiffening fingers.  A dull pain burned in his throat.  He lighted a match, and found the message that had lured Pat to his death in the other’s coat-pocket.  He rose and stumbled up the arroyo to his horse.

Halfway back to the ranch, and he met Ramon riding hard.  “Ride back,” said Waring.  “Hook up to the wagon and come to the arroyo.”

“Have you found the Senor Pat?”

“Yes.  He is dead.”

Ramon whirled his pony and pounded away in the darkness.

Out on the highway two long, slender shafts of light slid across the mesa, dipped into an arroyo, and climbed skyward as a machine buzzed up the opposite pitch.  The lights straightened again and shot on down the road, swinging stiffly from side to side.  Presently they came to a stop.  In the soft glow of their double radiance lay a yellow-wheeled buckboard, shattered and twisted round a telegraph pole.  The lights moved up slowly and stopped again.

A man jumped from the machine and walked round the buckboard.  Beneath it lay a crumpled figure.  The driver of the machine ran a quick hand over the neck and arms of Waco, who groaned.  The driver lifted him and carried him to the car.  Stacey lay some twenty miles behind him.  He was bound south.  The first town on his way was thirty miles distant.  But the roads were good.  He glanced back at the huddled figure in the tonneau.  The car purred on down the night.  The long shafts of light lifted over a rise and disappeared.
