at their own game, but their numbers were still scanty. Most of the frontiersmen were like Balthus—more of the settler than the woodsman type.
The sun had not set, but it was no longer in sight, hidden as it was behind the dense forest wall. The shadows were lengthening, deepening back in the woods as the companions strode on down the trail.
“It will be dark before we reach the fort,” commented Conan casually; then: “Listen!”
He stopped short, half crouching, sword ready, transformed into a savage figure of suspicion and menace, poised to spring and rend. Balthus had heard it too—a wild scream that broke at its highest note. It was the cry of a man in dire fear or agony.
Conan was off in an instant, racing down the trail, each stride widening the distance between him and his straining companion. Balthus puffed a curse. Among the settlements of the Tauran he was accounted a good runner, but Conan was leaving him behind with maddening ease. Then Balthus forgot his exasperation as his ears were outraged by the most frightful cry he had ever heard. It was not human, this one; it was a demoniacal caterwauling of hideous triumph that seemed to exult over fallen humanity and find echo in black gulfs beyond human ken.
Balthus faltered in his stride, and clammy sweat beaded his flesh. But Conan did not hesitate; he darted around a bend in the trail and disappeared, and Balthus, panicky at finding himself alone with that awful scream still shuddering through the forest in grisly echoes, put on an extra burst of speed and plunged after him.
The Aquilonian slid to a stumbling halt, almost colliding with the Cimmerian who stood in the trail over a crumpled body. But Conan was not looking at the corpse which lay there in the crimson-soaked dust. He was glaring into the deep woods on either side of the trail.
Balthus muttered a horrified oath. It was the body of a man which lay there in the trail, a short, fat man, clad in the gilt-worked boots and (despite the heat) the ermine-trimmed tunic of a wealthy merchant. His fat, pale face was set in a stare of frozen horror; his thick throat had been slashed from ear to ear as if by a razor-sharp blade. The short sword still in its scabbard seemed to indicate that he had been struck down without a chance to fight for his life.
“A Pict?” Balthus whispered, as he turned to peer into the deepening shadows of the forest.
Conan shook his head and straightened to scowl down at the dead man.
“A forest devil. This is the fifth, by Crom!”
“What do you mean?”
“Did you ever hear of a Pictish wizard called Zogar Sag?”
Balthus shook his head uneasily.
“He dwells in Gwawela, the nearest village across the river. Three months ago he hid beside this road and stole a string of pack-mules from a pack-train bound for the fort—drugged their drivers, somehow. The mules belonged to this man”—Conan casually indicated the corpse with his foot—“Tiberias, a merchant of Velitrium. They were loaded with ale-kegs, and old Zogar stopped to guzzle before he got across the river. A woodsman named Soractus trailed him, and led Valannus and three soldiers to where he lay dead drunk in a thicket. At the importunities of Tiberias, Valannus threw Zogar Sag into a cell, which is the worst insult you can give a Pict. He managed to kill his guard and escape, and sent back word that he meant to kill Tiberias and the five men who captured him in a way that would make Aquilonians shudder for centuries to come.
“Well, Soractus and the soldiers are dead. Soractus was killed on the river, the soldiers in the very shadow of the fort. And now Tiberias is dead. No Pict killed any of them. Each victim—except Tiberias, as you see—lacked his head—which no doubt is now ornamenting the altar of Zogar Sag’s particular god.”
“How do you know they weren’t killed by the Picts?” demanded Balthus.
Conan pointed to the corpse of the merchant.
“You think that was done with a knife or a sword? Look closer and you’ll see that only a talon could have made a gash like that. The flesh is ripped, not cut.”
“Perhaps a panther—” began Balthus, without conviction.
Conan shook his head impatiently.
“A man from the Tauran couldn’t mistake the mark of a panther’s claws. No. It’s a forest devil summoned by Zogar Sag to carry out his revenge. Tiberias was a fool to start for Velitrium alone, and so close to dusk. But each one of the victims seemed to be smitten with madness just before doom overtook him. Look here; the signs are plain enough. Tiberias came riding along the trail on his mule, maybe with a bundle of choice otter pelts behind his saddle to sell in Velitrium, and the thing sprang on him from behind that bush. See where the branches are crushed down.
“Tiberias gave one scream, and then his throat was torn open and he was selling his otter skins in Hell. The mule ran away into the woods. Listen! Even now you can hear him thrashing about under the trees. The demon didn’t have time to take Tiberias’ head; it took fright as we came up.”
“As you came up,” amended Balthus. “It must not be a very terrible creature if it flees from one armed man. But how do you know it was not a Pict with some kind of a hook that rips instead of slicing? Did you see it?”
“Tiberias was an armed man,” grunted Conan. “If Zogar Sag can bring demons to aid him, he can tell them which men to kill and which to let alone. No, I didn’t see it. I only saw the bushes shake as it left the trail. But if you want further proof, look here!”
The slayer had stepped into the pool of blood in which the dead man sprawled. Under the bushes at the edge of the path there was a footprint, made in blood on the hard loam.
“Did a man make that?” demanded Conan.
Balthus felt his scalp prickle. Neither man nor any beast that he had ever seen could have left that strange, monstrous, three-toed print, that was curiously combined of the bird and the reptile, yet a true type of neither. He spread his fingers above the print, careful not to touch it, and grunted explosively. He could not span the mark.
“What is it?” he whispered. “I never saw a beast that left a spoor like that.”
“Nor any other sane man,” answered Conan grimly. “It’s a swamp demon—they’re thick as bats in the swamps beyond Black River. You can hear them howling like damned souls when the wind blows strong from the south on hot nights.”
“What shall we do?” asked the Aquilonian, peering uneasily into the deep blue shadows. The frozen fear on the dead countenance haunted him. He wondered what hideous head the wretch had seen thrust grinning from among the leaves to chill his blood with terror.
“No use to try to follow a demon,” grunted Conan, drawing a short woodman’s ax from his girdle. “I tried tracking him after he killed Soractus. I lost his trail within a dozen steps. He might have grown himself wings and flown away, or sunk down through the earth to Hell. I don’t know. I’m not going after the mule, either. It’ll either wander back to the fort, or to some settler’s cabin.”
As he spoke Conan was busy at the edge of the trail with his ax. With a few strokes he cut a pair of saplings nine or ten feet long, and denuded them of their branches. Then he cut a length from a serpent-like vine that crawled among the bushes near by, and making one end fast to one of the poles, a couple of feet from the end, whipped the vine over the other sapling and interlaced it back and forth. In a few moments he had a crude
