Brill tried the one door of the but and found it bolted. He shouted to Lopez and received no answer. Yet utter silence did not reign. From within came a curious muffled worrying sound that ceased as Brill swung his pick crashing against the door. The flimsy portal splintered and Brill leaped into, the dark hut, eyes blazing, pick swung high for a desperate onslaught. But no, sound ruffled the grisly silence, and in the darkness nothing stirred, though Brill's chaotic imagination peopled the shadowed corners of the but with shapes of horror.
With a hand damp with perspiration he found a match and struck it. Besides himself only Lopez occupied the hut—old Lopez, stark dead on the dirt floor, arms spread wide like a crucifix, mouth sagging open in a semblance of idiocy, eyes wide and staring with a horror Brill found intolerable. The one window gaped open, showing the method of the slayer's exit —possibly his entrance as well. Brill went to that window and gazed out warily. He saw only the sloping hillside on one hand and the mesquite flat on the other. He starred—was that a hint of movement among the stunted shadows of the mesquites and chaparral—or had he but imagined he glimpsed a dim loping figure among the trees?
He turned back, as the match burned down to his fingers. He lit the old coal-oil lamp on the rude table, cursing as he burned his hand. The globe of the lamp was very hot, as if it had been burning for hours.
Reluctantly he turned to the corpse on the floor. Whatever sort of death had come to Lopez, it had been horrible, but Brill, gingerly examining the dead man, found no wound—no mark of knife or bludgeon on him. Wait. There was a thin smear of blood on Brill's questing hand. Searching, he found thesource—three or four tiny punctures in Lopezs throat, from which blood had oozed sluggishly. At first he thought they had been inflicted with a stiletto—a thin round edgeless dagger then he shook his head. He had seen stiletto wounds—he had the scar of one on his own body. These wounds more resembled the bite of some animal—they looked like the marks of pointed fangs.
Yet Brill did not believe they were deep enough to have caused death, nor had much blood flowed from them. A belief, abhorrent with grisly speculations, rose up in the dark corners of his mind—that Lopez had died of fright and that the wounds had been inflicted either simultaneously—with his death, or an instant afterward.
And Steve noticed something else; scrawled about on the floor lay a number of dingy leaves of paper, scrawled in the old Mexican's crude hand —he would write of the curse of the mound, he had said. There were the sheets on which he had written, there was the stump of a pencil on the floor, there was the hot lamp globe, all mute witnesses that the old Mexican had been seated at the roughhewn table writing for hours. Then it was not he who opened the moundchamber and stole the contents—but who was it, in God's name? And who or what was it that Brill had glimpsed loping over the shoulder of the hill?
Well, there was but one thing to do—saddle his mustang and ride the ten miles to Coyote Wells, the nearest town, and inform the sheriff of the murder.
Brill gathered up the papers. The last was crumpled in the old man's clutching hand and Brill secured it with some difficulty. Then as he turned to extinguish the light, he hesitated, and cursed himself for the crawling fear that lurked at the back of his mind—fear of the shadowy thing he had seen cross the window just before the light was extinguished in the hut. The long arm of the murderer, he thought, reaching for the lamp to put it out, no doubt. What had there been abnormal or inhuman about that vision, distorted though it must have been in the dim lamplight and shadow? As a man strives to remember the details of a nightmare dream, Steve tried to define in his mind some clear reason that would explain, why that flying glimpse had unnerved him to the extent of blundering headlong into a tree, and why the mere vague remembrance of it now caused cold sweat to break out on him.
Cursing himself to keep up his courage, he lighted his lantern, blew out the lamp on the rough table, and resolutely set forth, grasping his pick like a weapon. After all, why should certain seemingly abnormal aspects about a sordid murder upset him? Such crimes were abhorrent, but common enough, especially among Mexicans, who cherished unguessed feuds.
Then as he stepped into the silent starflecked night he brought up short. From across the creek sounded the sudden soul-shaking scream of a horse in deadly terror—then a mad drumming of hoofs that receded in the distance. And Brill swore in rage and dismay. Was it a pan lurking in the hills —had a monster cat slain old Lopez? Then why was not the victim marked with the scars of fierce hooked talons? And who extinguished the light in the but?
