She felt him start and shudder and sway and a moan broke from his lips as a searching, tearing thing ripped at the small of his back, burrowing devilishly into his very vitals. She clutched him closer, not understanding. "It's all I've got to give you," he muttered unnaturally. "My life's all I've got, ma'am. I'd be proud to give it.... It's a little thing to give to pay ... a debt like I owe you.... "You keep your body behind mine ... always ... until we get to the top...." "Tom!"--in alarm. "You're hit.... Oh, Tom!" She shook him, hitching herself about that she might see his face. "Tom!" "A scratch," he said. "Just a--" The horse threw up his head and recoiled as a bullet sang past. "A--scratch," he finished. The girl looked about wildly. She knew there was no shelter there, not a ledge behind which they could hide, not a tree that would screen them. The wall rose straight on one side, fell sheer on the other. There was no place to go but up; they could not turn there and go down for there was no room ... the pinto, shot through the belly, had tried that! The firing below grew more rapid. It did not wait for the lightning flashes now. Those spats of yellow fire struck upward continuously; in darkness, blindly; in light searching intelligently as the riders moved upward, nearer safety. HC men closed in on those who shot at the figures on the trail, aiming at the flurries of viper light, meeting counter fire as they drew nearer the murderous group of men. "Fireflies!" Beck muttered as he looked down again. "Lightnin' bugs let loose from hell!" When there was no fire in the clouds those light points looked so harmless, down there in the soft, velvet darkness! Well they might have been insects, bedecking a summer night ... but from them came the whining, droning, searching projectiles that flew to find his life and Jane Hunter's life! Fifty yards further was the first rise of rock that would protect them from below. Fifty yards, and the horse, under added burden, was sobbing as he staggered. Beck swayed forward and regained his balance with an effort that cost him a groan, but his arms, tight about Jane Hunter's body did not relax a trifle; they held like tough, green wood. The girl cried out to him again, that he was hurt.... "It's nothin', ... my life," he replied. "It's all I could do ... for doubtin' you. I couldn't ask you to ... love me.... I could die for you ... that's all, ma'am...." "Tom, Tom! Keep your head; keep your head one minute longer; we'll be safe.... Safe, then...." Thirty yards to the place where the trail ran between uprising walls of rock; thirty yards to that shelter; thirty yards to safety.... But she looked down at those deadly fireflies playing on the flat, and did not see a hatless man, crouched forward, run down the trail toward them, pistol in his hand....
