Venters looked quickly from the fallen rustlers to the cañon where the others had disappeared. He calculated on the time needed for running horses to return to the open, if their riders heard shots. He waited breathlessly. But the estimated time dragged by and no riders appeared. Venters began presently to believe that the rifle reports had not penetrated into the recesses of the cañon, and felt safe for the immediate present. He hurried to the spot where the first rustler had been dragged by his horse. The man lay in deep grass, dead, jaw fallen, eyes protruding—a sight that sickened Venters. The first man at whom he had ever aimed a weapon he had shot through the heart. With the clammy sweat oozing from every pore Venters dragged the rustler in among some boulders and covered him with slabs of rock. Then he smoothed out the crushed trail in grass and sage. The rustler’s horse had stopped a quarter of a mile off and was grazing. When Venters rapidly strode toward the Masked Rider not even the cold nausea that gripped him could wholly banish curiosity. For he had shot Oldring’s infamous lieutenant, whose face had never been seen. Venters experienced a grim pride in the feat. What would Tull say to this achievement of the outcast who rode too often to Deception Pass? Venters’s curious eagerness and expectation had not prepared him for the shock he received when he stood over a slight, dark figure. The rustler wore the black mask that had given him his name, but he had no weapons. Venters glanced at the drooping horse, there were no gun-sheaths on the saddle. “A rustler who didn’t pack guns!” muttered Venters. “He wears no belt. He couldn’t pack guns in that rig.... Strange!” A low, gasping intake of breath and a sudden twitching of body told Venters the rider still lived. “He’s alive!... I’ve got to stand here and watch him die. And I shot an unarmed man.” Shrinkingly Venters removed the rider’s wide sombrero and the black cloth mask. This action disclosed bright chestnut hair, inclined to curl, and a white, youthful face. Along the lower line of cheek and jaw was a clear demarcation, where the brown of tanned skin met the white that had been hidden from the sun. “Oh, he’s only a boy!... What! Can he be Oldring’s Masked Rider?” [Illustration: “Oh, he’s only a boy!... What! Can he be Oldring’s Masked Rider?”] The boy showed signs of returning consciousness. He stirred; his lips moved; a small brown hand clenched in his blouse. Venters knelt with a gathering horror of his deed. His bullet had entered the rider’s right breast, high up to the shoulder. With hands that shook, Venters untied a black scarf and ripped open the blood-wet blouse. First he saw a gaping hole, dark red against a whiteness of skin, from which welled a slender red stream. Then the graceful, beautiful swell of a woman’s breast! “A woman!” he cried. “A girl!... I’ve killed a girl!”
