There slipped into the light of the fire a little round gleaming tube of steel. Six inches beyond the doorway was it thrust, then held still and steady. Jack knew it for the muzzle of a Mannlicher, and realised with a swelling heart what it meant. He turned his eyes on the dark face of the Ruby King, who, with an air of infinite enjoyment, was giving the writhing reptile a little and a little more liberty, and Jack knew that U Saw was a dead man. A moment later the rifle spoke. There was a sharp jet of flame, a crack, and a scream. The three were practically simultaneous, and the scream rose from the wildly-parted lips of the Ruby King as he whirled round and staggered against Saya Chone, a slip of lead driven through his brain. The fate of the half-caste was striking and dreadful. The mortally-smitten man flung out his right arm, and the cobra was swung full against the man who stood beside him, and, at the same instant, the Ruby King's grasp was loosened. Here was the chance for which the creature, irritated to the utmost fury, had longed. It struck, struck with all its might, and drove its deadly fangs deep into the throat of the half-caste. The latter staggered back with a frightful yell, and tore the horrible reptile from its grip, and cast it away. But the work was done, and the full-filled poison sacs had emptied their store of venom into the blood of Saya Chone. All this happened in an instant, in the twinkling of an eye; and before a hand could be lifted among the retainers, a whirling hurricane of lead smote with crushing fury among the close-packed group of Kachins which had been clustered behind the leaders. A stream of bullets was poured into them as swiftly as magazines could be worked, and half their number went down headlong. None of the rest stayed to face this awful and mysterious foe. To them it seemed as if evil spirits must be encompassing their destruction, and they fled from this dreadful attack, which leapt upon them so suddenly from the darkness and the silence. Those who could move ran for a low place in the ruined wall, climbed it frantically, and fled into the darkness, yelling and terror-stricken. Now there burst into the courtyard three familiar figures. Buck Risley led the way, Jim Dent followed, and Me Dain raced after. "Say," cried Buck, "we only dropped on this little fandango just in time. Stand steady, Jack." With a few swift strokes of his knife he severed Jack's bonds, and the English lad staggered aside, and was caught by his father. They exchanged a strong, silent hand-grip, but neither could speak. Jim Dent, a reloaded Mauser pistol in hand, was standing on guard. But they had nothing to fear from the groaning wounded, nothing from the Ruby King who lay with his evil smile fixed for ever on his dark face, nothing from the half-caste, now writhing in the agonies of a terrible death.
