"Wonder who the three were with Plimsoll? They've gone to the Hideout an' we got to find it, li'l' hawss. Some job, I reckon. But Plimsoll's goin' to be mighty sorry fo' himse'f befo' long."

As they neared the foot-hills of the range he lapsed to silence. He was taking chances, crossing country this fashion. He knew it fairly well, and he guessed at what lay behind the visible contours from the experience of years. Deep barrancas might crop up in their path, massed thickets of cactus that had to be ridden around for loss of time. The mesa, looking like a solid block of rock at a distance, was, he knew well, broken into tortuous ravines and cañons, eroded into wild thrusts of the mother rock, its central part eaten away by time and weather.

Part of the Three Star range, shared by two ranches, ran over the southern part of the mesa and it was close to its boundary fence that Sandy was heading. Then came the range of Plimsoll's Waterline, a rough country, unknown to Sandy, with scant food for many cattle, but sweet grass enough for a horse herd and containing pockets where the slicktails sometimes came.

Sandy struck the first rise. He was now a crucible filled with glowing white fury. Thoughts of what Plimsoll might achieve in insult and injury to Molly could not be kept out of his mind and they but added fuel. It was not Sandy Bourke of the Three Bar, riding his favorite pinto, but a desperate man on a horse infected with the same grim determination, a man with a face that, despite the fiery heat within, blazing from his eyes, would have chilled the blood of any meeting him.

He did not spare Pronto nor did Pronto attempt to spare himself, going at the task set before him with all the superb coordination of muscle and tendon and bone that he possessed. They slid down the sides of ravines that were almost as steep as a wall, the pinto squatting on its tail; they climbed the opposing banks with the surety of a mountain goat, a rush, a scramble of well-placed hooves, a play of fetlocks; then, with a heave of spreading ribs and hammer-strokes of a gallant heart under Sandy's lean thighs, they were over the top and away, with Sandy's eyes searching the land for the shortest, most practical way.

The place it had taken Molly and young Keith nearly three hours to reach in leisurely fashion, Sandy gained in one, splashing through the shallows of Willow Creek at the ford below the big bend and giving Pronto the chance to cool his fetlocks and rinse out his mouth in the cold water.

Ahead lay the chimney ravine that led around into Beaver Dam Lake, in which Molly and the boy had been attacked. Sandy viewed the chaparral, the trees that covered the lesser slopes, the stark cliffs above. Part of this lay in the Waterline territory. The chances that Plimsoll had left some one on guard were not to be slighted. But he rode on down the narrow trail. Once in a while he broke a branch and left it swinging as a guide to Sam when he should follow with the riders from the ranch. They would be coming in now and in a few minutes would start on remounts. Perhaps Brandon had come? Sandy wasted little time on surmise.

The tracks of Molly's Blaze and the horse Donald had been riding were plain as print to Sandy. He even noticed the slot of Grit's pads here and there in softer soil. He had picked them up at the coming-out place of the ford. Two more sets of hoofs came out of the chaparral and from there on the sign was badly broken. But Sandy knew the story and the interpretation was sufficient.

The shadows were getting longer, half the eastern side of the ravine was in shadow that steadily crept down as if to obliterate the telltale imprints. The moon was slowly brightening. Sandy's eyes, burning steadily, were untroubled by doubt.

The place of the struggle was plain. The brush was trampled. To one side of the trail there was a clot of blood, almost black, with flies buzzing attention to it. It must have come from Grit. He caught sight of another fleck of it on some leaves where Grit had raced into the brush out of the way of the crippling fire.
