He hurried from his shack, the swinging lantern casting long distorted shadows ahead of him and behind. He chuckled as he visualized Lopez's thoughts and actions when he learned, on the morrow, that the forbidden mound had been pried into. A good thing he opened it that evening, Brill reflected; Lopez might even have tried to prevent him meddling with it, had he known.
In the dreamy hush of the summer night, Brill reached the mound—lifted his lantern—swore bewilderedly. The lantern revealed his excavations, his tools lying carelessly where he had dropped them—and a black gaping aperture! The great blocking stone lay in the bottom of the excavation he had made, as if thrust carelessly aside. Warily he thrust the lantern forward and peered into the small cave-like chamber, expecting to see he knew not what. Nothing met his eyes except the bare rock sides of a long narrow cell, large enough to receive a man's body, which had apparently been built up of roughly hewn square-cut stones, cunningly and strongly joined together.
"Lopez!" exclaimed Steve furiously. "The dirty coyote! He's been watchin' me work—and when I went after the lantern, he snuck up and pried the rock outand grabbed whatever was in there, I reckon. Blast his greasy hide, I'll fix him!"
Savagely he extinguished the lantern and glared across the shallow, brush- grown valley. And as he looked he stiffened. Over the corner of the hill, on the other side of which the shack of Lope z stood, a shadow moved. The slender moon was setting, the light dim and the play of the shadows baffling. But Steve's eyes were sharpened by the sun and winds of the wastelands, and he knew that it was some two-legged creature that was disappearing over the low shoulder of the mesquite-grown hill.
"Beatin' it to his shack," snarled Brill. "He's shore got somethin' or he wouldn't be travelin' at that speed."
Brill swallowed, wondering why a peculiar trembling had suddenly taken hold of him. What was there unusual about a thieving old greaser running home with his loot? Brill tried to drown the feeling that there was something peculiar about the gait of the dim shadow, which gad seemed to move at a sort of slinking lope. There, must have been need for swiftness when stocky old Juan Lopez elected to travel at such a strange pace.
"Whatever he found is as much mine as his," swore Brill, trying to get his mind off the abnormal aspect of the figure's flight, "I got this land leased and I done all the work diggin'. A curse, heck! No wonder he told me that stuff. Wanted me to leave it alone so he could get it hisself. It's a wonder he ain't dug it up long before this. But you can't never tell about them spigs."
Brill, as he meditated thus, was striding down the gentle slope of the pasture which led down to the creek bed. He passed into the shadows of the trees and dense underbrush and walked across the dry creek bed, noting absently that neither whippoorwill nor hoot-owl called in the darkness. There was a waiting, listening tenseness in the night that he did not like. The shadows in the creek bed seemed too thick, too breathless. He wished he had not blown out the lantern, which he still carried, and was glad he had brought the pick, gripped like a battle-ax in his right hand. He had an impulse to whistle, just to break the silence, then swore and dismissed the thought. Yet he was glad when he clambered up the low opposite bank and emerged into the starlight.
He walked up the slope and onto the hill, and looked down on the mesquite flat wherein stood Lopezs squalid hut. A light showed at the one window.
"Packin' his things for a getaway, I reckon," grunted Steve. "Oh, what the—"
He staggered as from a physical impact as a frightful scream knifed the stillness. He wanted to clap his hands over his ears to shut out the horror of that cry, which rose unbearably and then broke in an abhorrent gurgle.
"Good God!" Steve felt the cold sweat spring out upon him. "Lopez—or somebody—"
Even as he gasped the words he was running down the hill as fast as his long legs could carry him. Some unspeakable horror was taking place in that lonely hut, but he was going to investigate if it meant facing the Devil himself. He tightened his grip on his pick-handle as he ran. Wandering prowlers, murdering old Lopez for the loot he had taken from the mound, Steve thought, and forgot his wrath. It would go hard for anyone he found molesting the old scoundrel, thief though he might be.
He hit the flat, running hard.. And then the light in the but went out and Steve staggeed in full flight, bringing up against a mesquite tree with an impact that jolted a grunt out of him and tore his hands on the thorns. Rebounding with a sobbed curse, he rushed for the shack, nerving himself for what he might see—his hair still standing on end at what he had already seen.
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
