Not a night for a dog certainly; but for a man, with a man's work before him? Belle would bid him go, he knew. A minute later he had closed the door behind him, and faced the Pass again. Ere he reached the end of the short ascent it was snowing gently; then, with a furious blast, hailing in slanted torrents that glittered like dew-drops in the almost ceaseless shiver of the silent lightning. Everything was so silent, save for the wind which, caught and twisted in the gullies, moaned as if in pain. Ah! was that the end of all things? Round him, in him, through him, came a blaze of white flame, making him stagger against the wall of rock and throw up his hands as if to ward off the impalpable mist which held such a deadly weapon. Half-blinded he went on, his mind full of one thought. If that sort of thing came again, say when he was passing the snow-bridge, could a man stand it without a start which must mean instant death? The question left no room for anything save a vague wonder till it was settled in the affirmative. Then the nickname of "lightning-_wallahs_," given by the natives to the telegraph-clerks, struck him as being happy, and Afzul's reference to fire from heaven passed through his mind. More like fire from hell surely, with that horrible sulphurous smell, and now and again a ghastly undertoned crackle like the laughter of fiends. There again! Wider this time, and followed by a rattle as of musketry. But the snow which was now sweeping along in white swirls seemed to shroud even the lightning. Horrible! To have so much light and to be able to see nothing but cloud, and the stones at your feet. How long would he see them? How long would it be before the snow obliterated the path, leaving him lost? He stumbled along, tingling to his very finger-tips, despite the cold which grew with every explosion. The very hair on his fur coat stood out electrified, and his brain swam with a wild excitement. On and on recklessly, yet steadily; his footsteps deadened by the drifting snow, until he stood at the threshold of shelter and threw open the door of the shanty. Great Heaven, what was this! The _bâbu_, green with fear, working the signaller, while Afzul Khân, surrounded by six or seven armed Pathans, stood over him with drawn knife. "Go on, you fool!" he was saying, "your work is nearly finished." The full meaning of the scene flashed through Dick Smith's excited brain quicker than any lightning. Treachery was at work, with a coward for its agent. His revolver was out in a second, and before the astonished group had time to grasp the unexpected interruption, the _bâbu's_ nerveless fingers slipped from the handles, as with a gasping sob, rising above the report, he sank in a heap on the floor. "By God and His Prophet!" cried Afzul, carried away, as men of his kind are, by the display of daredevil boldness which is their unattained ideal of bravery. "Yea, by the twelve Imaums, but it was well done."
