Stephen King called Pigeons from Hell "one of the finest horror stories of our century." It's not too long of a story, but I'm posting it in three parts because that's how the author divided it up (Part 1 can be found here). The author is Robert E Howard, who created Conan the Barbarian. Fun read for a late night, especially if you're in a pine forest in the South.

Part 2: The Snake's Brother

Again the shadows were lengthening over the pinelands, and again two men came bumping along the old road in a car with a New England license plate.
Buckner was driving. Griswell's nerves were too shattered for him to trust himself at the wheel. He looked gaunt and haggard, and his face was still pallid. The strain of the day spent at the county-seat was added to the horror that still rode his soul like the shadow of a black-winged vulture. He had not slept, had not tasted what he had eaten.
"I told you I'd tell you about the Blassenvilles," said Buckner. "They were proud folks, haughty, and pretty damn ruthless when they wanted their way. They didn't treat their help as well as other planters did—got their ideas in the West Indies, I reckon. There was a streak of cruelty in them—especially Miss Celia, the last one of the family to come to these parts. That was long after the slaves had been freed, but she used to whip her mulatto maid just like she was a slave, the old folks say.... The Negroes said when a Blassenville died, the devil was always waitin' for him out in the black pines.
"Well, after the Civil War they died off pretty fast livin' in poverty on the plantation which was allowed to go to ruin. Finally only four girls were left, sisters, livin' in the old house and ekin' out a bare livin', with a few Negroes livin' in the old slave huts and workin' the fields on the share. They kept to themselves, bein' proud, and ashamed of their poverty. Folks wouldn't see them for months at a time. When they needed supplies they sent a Negro to town after them.
"But folks knew about it when Miss Celia came to live with them. She came from somewhere in the West Indies, where the whole family originally had its roots—a fine, handsome woman, they say, in the early thirties. But she didn't mix with folks any more than the girls did. She brought a mulatto maid with her, and the Blassenville cruelty cropped out in her treatment of this maid.
"I knew an old Negro years ago, who swore he saw Miss Celia tie this girl up to a tree, stark naked, and whip her with a horse-whip. Nobody was surprised when she disappeared. Everybody figured she'd run away, of course.
"Well, one day in the spring of 1890 Miss Elizabeth, the youngest girl, came in to town for the first time in maybe a year. She came after supplies. Said the Negroes had all left the place. Talked a little more, too, a bit wild. Said Miss Celia had gone, without leaving any word. Said her sisters thought she'd gone back to the West Indies, but she believed her aunt was still in the house. She didn't say what she meant. Just got her supplies and pulled out for the Manor.
"A month went past, and a Negro came into town and said that Miss Elizabeth was livin' at the Manor alone. Said her three sisters weren't there any more, that they'd left one by one without givin' any word or explanation. She didn't know where they'd gone, and was afraid to stay there alone, but didn't know where else to go. She'd never known anything but the Manor, and had neither relatives nor friends. But she was in mortal terror of something. The Negro said she locked herself in her room at night and kept candles burnin' all night....
"It was a stormy spring night when Miss Elizabeth came tearin' into town on the one horse she owned, nearly dead from fright. She fell from her horse in the square; when she could talk she said she'd found a secret room in the Manor that had been forgotten for a hundred years. And she said that there she found her three sisters, dead, and hangin' by their necks from the ceilin'. She said something chased her and nearly brained her with an ax as she ran out the front door, but somehow she got to the horse and got away. She was nearly crazy with fear, and didn't know what it was that chased her—said it looked like a woman with a yellow face.
"About a hundred men rode out there, right away. They searched the house from top to bottom, but they didn't find any secret room, or the remains of the sisters. But they did find a hatchet stickin' in the doorjamb downstairs, with some of Miss Elizabeth's hairs stuck on it, just as she'd said. She wouldn't go back there and show them how to find the secret door; almost went crazy when they suggested it.
"When she was able to travel, the people made up some money and loaned it to her—she was still too proud to accept charity—and she went to California. She never came back, but later it was learned, when she sent back to repay the money they'd loaned her, that she'd married out there.
"Nobody ever bought the house. It stood there just as she'd left it, and as the years passed folks stole all the furnishings out of it, poor white trash, I reckon. A Negro wouldn't go about it. But they came after sun-up and left there long before sun-down."
"What did the people think about Miss Elizabeth's story?" asked Griswell.
"Well, most folks thought she'd gone a little crazy, livin' in that old house alone. But some people believed that mulatto girl, Joan, didn't run away, after all. They believed she'd hidden in the woods, and glutted her hatred of the Blassenvilles by murderin' Miss Celia and the three girls. They beat up the woods with bloodhounds, but never found a trace of her. If there was a secret room in the house, she might have been hidin' there—if there was anything to that theory."
"She couldn't have been hiding there all these years," muttered Griswell. "Anyway, the thing in the house now isn't human."
Buckner wrenched the wheel around and turned into a dim trace that left the main road and meandered off through the pines.
"Where you going?"
"There's an old Negro that lives off this way a few miles. I want to talk to him. We're up against something that takes more than white man's sense. The black people know more than we do about some things. This old man is nearly a hundred years old. His master educated him when he was a boy, and after he was freed he traveled more extensively than most white men do. They say he's a voodoo man."
Griswell shivered at the phrase, staring uneasily at the green forest walls that shut them in. The scent of the pines was mingled with the odors of unfamiliar plants and blossoms. But underlying all was a reek of rot and decay. Again a sick abhorrence of these dark mysterious woodlands almost overpowered him.
"Voodoo!" he muttered. "I'd forgotten about that—I never could think of black magic in connection with the South. To me witchcraft was always associated with old crooked streets in waterfront towns, overhung by gabled roofs that were old when they were hanging witches in Salem; dark musty alleys where black cats and other things might steal at night. Witchcraft always meant the old towns of New England, to me—but all this is more terrible than any New England legend—these somber pines, old deserted houses, lost plantations, mysterious black people, old tales of madness and horror—God, what frightful, ancient terrors there are on this continent fools call 'young'!"
"Here's old Jacob's hut," announced Buckner, bringing the automobile to a halt.
Griswell saw a clearing and a small cabin squatting under the shadows of the huge trees. There pines gave way to oaks and cypresses, bearded with gray trailing moss, and behind the cabin lay the edge of a swamp that ran away under the dimness of the trees, choked with rank vegetation. A thin wisp of blue smoke curled up from the stick-and-mud chimney.
He followed Buckner to the tiny stoop, where the sheriff pushed open the leather-hinged door and strode in. Griswell blinked in the comparative dimness of the interior. A single small window let in a little daylight. An old Negro crouched beside the hearth, watching a pot stew over the open fire.
He looked up as they entered, but did not rise. He seemed incredibly old. His face was a mass of wrinkles, and his eyes, dark and vital, were filmed momentarily at times as if his mind wandered.
Buckner motioned Griswell to sit down in a string-bottomed chair, and himself took a crudely-made bench near the hearth, facing the old man.
"Jacob," he said bluntly, "the time's come for you to talk. I know you know the secret of Blassenville Manor. I've never questioned you about it, because it wasn't in my line. But a man was murdered there last night, and this man here may hang for it, unless you tell me what haunts that old house of the Blassenvilles."
The old man's eyes gleamed, then grew misty as if clouds of extreme age drifted across his brittle mind.
"The Blassenvilles," he murmured, and his voice was mellow and rich; his speech not the patois of the piny woods darky. "They were proud people, sirs—proud and cruel. Some died in the war, some were killed in duels—the men-folks, sirs. Some died in the Manor—the old Manor—" His voice trailed off into unintelligible mumblings.
"What of the Manor?" asked Buckner patiently.
"Miss Celia was the proudest of them all," the old man muttered. "The proudest and the crudest. The black people hated her; Joan most of all. Joan had white blood in her, and she was proud, too. Miss Celia whipped her like a slave."
"What is the secret of Blassenville Manor?" persisted Buckner.
The film faded from the old man's eyes; they were dark as moonlit wells.
"What secret, sir? I do not understand."
"Yes, you do. For years that old house has stood there with its mystery. You know the key to its riddle."
The old man stirred the stew. He seemed perfectly rational now.
"Sir, life is sweet, even to an old black man."
"You mean somebody would kill you if you told me?"
But the old man was mumbling again, his eyes clouded.
"Not somebody. No human. No human being. The black gods of the swamps. My secret is inviolate, guarded by the Big Serpent, the god above all gods. He would send a little brother to kiss me with his cold lips—a little brother, with a white crescent moon on his head. I sold my soul to the Big Serpent when he made me maker of zuvembies—"
Buckner stiffened.
"I heard that word once before," he said softly, "from the lips of a dying black man, when I was a child. What does it mean?"
Fear filled the eyes of old Jacob.
"What have I said? No—no! I said nothing."
"Zuvembies," prompted Buckner.
"Zuvembies," mechanically repeated the old man, his eyes vacant. "A zuvembie was once a woman—on the Slave Coast they know of them. The drums that whisper by night in the hills of Haiti tell of them. The makers of zuvembies are honored of the people of Damballah.
"It is death to speak of it to a white man—it is one of the Snake God's forbidden secrets."
"You speak of the zuvembies," said Buckner softly.
"I must not speak of it," mumbled the old man, and Griswell realized that he was thinking aloud, too far gone in his dotage to be aware that he was speaking at all. "No white man must know that I danced in the Black Ceremony of the voodoo, and was made a maker of zombies and zuvembies. The Big Snake punishes loose tongues with death."
"A zuvembie is a woman?" prompted Buckner.
"Was a woman," the old Negro muttered. "She knew I was a maker of zuvembies—she came and stood in my hut and asked for the awful brew—the brew of ground snake-bones, and the blood of vampire bats, and the dew from a night-hawk's wings, and other elements unnameable. She had danced in the Black Ceremony—she was ripe to become a zuvembie—the Black Brew was all that was needed—the other was beautiful—I could not refuse her."
"Who?" demanded Buckner tensely, but the old man's head was sunk on his withered breast, and he did not reply. He seemed to slumber as he sat. Buckner shook him. "You gave a brew to make a woman a zuvembie—what is a zuvembie?"
The old man stirred resentfully and muttered drowsily.
"A zuvembie is no longer human. It knows neither relatives nor friends. It is one with the people of the Black World. It commands the natural demons—owls, bats, snakes and werewolves, and can fetch darkness to blot out a little light. It can be slain by lead or steel, but unless it is slain thus, it lives forever, and it eats no such food as humans eat. It dwells like a bat in a cave or an old house. Time means naught to the zuvembie; an hour, a day, a year, all is one. It cannot speak human words, nor think as a human thinks, but it can hypnotize the living by the sound of its voice, and when it slays a man it can command his lifeless body until the flesh is cold. As long as the blood flows, the corpse is its slave. Its pleasure lies in the slaughter of human beings."
"And why should one become a zuvembie?" asked Buckner softly.
"Hate," whispered the old man. "Hate! Revenge!"
"Was her name Joan?" murmured Buckner.
It was as if the name penetrated the fogs of senility that clouded the voodoo-man's mind.
He shook himself and the film faded from his eyes, leaving them hard and gleaming as wet black marble.
"Joan?" he said slowly. "I have not heard that name for the span of a generation. I seem to have been sleeping, gentlemen; I do not remember—I ask your pardon. Old men fall asleep before the fire, like old dogs. You asked me of Blassenville Manor? Sir, if I were to tell you why I cannot answer you, you would deem it mere superstition. Yet the white man's God be my witness—"
As he spoke he was reaching across the hearth for a piece of firewood, groping among the heaps of sticks there. And his voice broke in a scream, as he jerked back his arm convulsively. And a horrible, thrashing, trailing thing came with it. Around the voodoo-man's arm a mottled length of that shape was wrapped, and a wicked wedge-shaped head struck again in silent fury.
The old man fell on the-hearth, screaming, upsetting the simmering pot and scattering the embers, and then Buckner caught up a billet of firewood and crushed that flat head. Cursing, he kicked aside the knotting, twisting trunk, glaring briefly at the mangled head.
Old Jacob had ceased screaming and writhing; he lay still, staring glassily upward.
"Dead?" whispered Griswell.
"Dead as Judas Iscariot," snapped Buckner, frowning at the twitching reptile. "That infernal snake crammed enough poison into his veins to kill a dozen men his age. But I think it was the shock and fright that killed him."
"What shall we do?" asked Griswell, shivering.
"Leave the body on that bunk. Nothin' can hurt it, if we bolt the door so the wild hogs can't get in, or any cat. We'll carry it into town tomorrow. We've got work to do tonight. Let's get goin'."
Griswell shrank from touching the corpse, but he helped Buckner lift it on the rude bunk, and then stumbled hastily out of the hut. The sun was hovering above the horizon, visible in dazzling red flame through the black stems of the trees.
They climbed into the car in silence, and went bumping back along the stumpy train.
"He said the Big Snake would send one of his brothers," muttered Griswell.
"Nonsense!" snorted Buckner. "Snakes like warmth, and that swamp is full of them. It crawled in and coiled up among that firewood. Old Jacob disturbed it, and it bit him. Nothin' supernatural about that." After a short silence he said, in a different voice, "That was the first time I ever saw a rattler strike without singin'; and the first time I ever saw a snake with a white crescent moon on its head."
They were turning in to the main road before either spoke again.
"You think that the mulatto Joan has skulked in the house all these years?" Griswell asked.
"You heard what old Jacob said," answered Buckner grimly. "Time means nothin' to a zuvembie."
As they made the last turn in the road, Griswell braced himself against the sight of Blassenville Manor looming black against the red sunset. When it came into view he bit his lip to keep from shrieking. The suggestion of cryptic horror came back in all its power.
"Look!" he whispered from dry lips, as they came to a halt beside the road. Buckner grunted.
From the balustrades of the gallery rose a whirling cloud of pigeons that swept away into the sunset, black against the lurid glare.
