The murderer turned from his reverie with hands extended and trembling; the snow was not more bleached than his bloodless face, and his feet grew slippery and infirm. An alcove, which he had not marked, was hewn in the brow of the precipice. It had been intended to shelter pilgrims from the wind and the snow; and there, wrapped in his buff garments, whose hue, assimilating to that of the rock, absorbed him from detection, stood a witness to the deed--the guard to the diligence--none other than Auburn Risque. For an instant only the accused shrank back. Then his body grew short and compact; he was gathering himself up for a life-struggle. "Hold off!" said Risque, in his old, hard, measured way; "we guards go armed; if you move, I shall scatter your brains in the snow; if I miss you, a note of this whistle will summon my postilions." The cold face was never more emotionless; he held a revolver in his hand, and kept the other in his blank, spotted eye, as if locating the vital parts with the end to bring him down at a shot. "You do not play well," said Risque at length, when the other, ghastly white, sat speechless upon the parapet; "if you were the student of chance, that I have been, you would know that at murder the odds are always against you!" "You will not betray me?" pleaded Plade; "so inveterate a gamester can have no conventional ideas of life or crime. I am ready to pay for your discretion with half my winnings." "I am a gambler," said Risque, curtly; "not an assassin! I always give my opponents fair show. But I will not touch blood-money." "What fair show do you give me?" "Two hours' start. I am responsible for my passengers. Go on, unharmed, if you will. But at Hospice I shall proclaim you. Every moment that you falter spins the rope for your gallows!" Plade did not dally, but took to flight at once. He climbed by the angles of the terraces, and saw the diligence far below tugging up the circuitous road. He ran at full speed; no human being was abroad besides, but yet there were other footfalls in the snow, other sounds, as of a man breathing hard and pursued upon the lonely mountain. The fugitive turned--once, twice, thrice; he laughed aloud, and shook his clenched hand at the sky. Still the flat, dead tramp followed close behind, and the pace seemed not unfamiliar. It could not be--his blood ceased to circulate, and stood freezing at the thought--was it the march, the tread of Hugenot? He dropped a loud curse, like a howl, and kept upon his way. The footfalls were as swift; he saw their impressions at his heels--prints of a small, lithe, human foot, made by no living man. He shut his eyes and his ears, but the consciousness remained, the inexplicable phenomenon of some invisible but familiar thing which would not leave him; which made its register as it passed; which no speed could outstrip, no argument exorcise. Was it a sick fancy, a probed heart, or did the phantom of the dead man indeed give chase?
