His ears told him that the slug was close behind. Perhaps it was gaining. He dared not turn to look, lest he trip over some marble fragment and go sprawling; the monster would be upon him before he could regain his feet.
Again came that spitting sound. Conan leaped frantically to one side; again the jet of liquid flashed past him. Even if he kept ahead of the slug all the way to the city wall, the next shot would probably hit its mark.
Conan dodged around a corner to put obstacles between himself and the slug. He raced down a narrow zigzag street, then around another corner.
He was lost in the maze of streets, he knew; but the main thing was to keep turning corners so as not to give his pursuer another clear shot at him. The sucking sounds and the stench indicated that it was following his trail. Once, when he paused to catch his breath, he looked back to see the slug pouring around the last corner he had turned.
On and on he went, dodging this way and that through the maze of the ancient city. If he could not outrun the slug, perhaps he could tire it. A man, he knew, could outlast almost any animal in a long-distance run. But the slug seemed tireless.
Something about the buildings he was passing struck him as familiar.
Then he realized that he was coming to the half-ruined temple he had passed just before he met the slug. A quick glance showed him that the upper parts of the building could be reached by an active climber.
Conan bounded up a pile of rubbish to the top of the broken wall.
Leaping from stone to stone, he made his way up the jagged profile of the wall to an unruined section facing the street. He found himself on a stretch of roof behind the row of marble gargoyles. He approached them, treading softly lest the half-ruined roof collapse beneath him and detouring around holes through which a man could fall into the chambers below.
The sound and smell of the slug came to him from the street. Realizing that it had lost his track and uncertain as to which way to turn, the creature had evidently stopped in front of the temple. Very cautiously—for he was sure the slug could see him in the moonlight—Conan peered past one of the statues and down into the street.
There lay the great, grayish mass, on which the moon shone moistly. The eye stalks wavered this way and that, seeking the creature's prey.
Beneath them, the shorter horns swept back and forth a little above the ground, as if smelling for the Cimmerian's trail.
Conan felt certain that the slug would soon pick up his trail. He had no doubt that it could slither up the sides of the building quite as readily as he had climbed it.
He put a hand against a gargoyle—a nightmarish statue with a humanoid body, bat's wings, and a reptilian head— and pushed. The statue rocked a trifle with a faint crunching noise.
At the sound, the horns of the slug whipped upward toward the roof of the temple. The slug's head came around, bending its body into a sharp curve. The head approached the front of the temple and began to slide up one of the huge pillars, directly below the place where Conan crouched with bared teeth.
A sword, Conan thought, would be of little use against such a monstrosity. Like other lowly forms of life, it could survive damage that would instantly destroy a higher creature.
Up the pillar came the slug's head, the eyes on their stalks swiveling back and forth. At the present rate, the monster's head would reach the edge of the roof while most of its body still lay in the street below.
Then Conan saw what he must do. He hurled himself at the gargoyle. With a mighty heave, he sent it tumbling over the edge of the roof. Instead of the crash that such a mass of marble would ordinarily make on striking the pavement, there floated up the sound of a moist, squashy impact, followed by a heavy thud as the forward part of the slug's body fell back to earth.
When Conan risked a glance over the parapet, he saw that the statue had sunk into the slug's body until it was almost buried. The great, gray mass writhed and lashed like a worm on a fisherman's hook. A blow of the tail made the front of the temple tremble; somewhere in the interior a few loose stones fell clattering. Conan wondered if the whole structure were about to collapse beneath him, burying him in the debris.
"So much for you!" snarled the Cimmerian.
He went along the row of gargoyles until he found another that was loose and directly over part of the slug's body. Down it went with another squashing impact. A third missed and shattered on the pavement.
A fourth and smaller statue he picked bodily up and, muscles cracking with the strain, hurled outward so that it fell on the writhing head.
As the beast's convulsions slowly subsided, Conan pushed over two more gargoyles to make sure. When the body no longer writhed, he clambered down to the street. He approached the great, stinking mass cautiously, sword out. At last, summoning all his courage, he slashed into the rubbery flesh. Dark ichor oozed out, and rippling morions ran through the wet, gray skin. But, even though parts might retain signs of independent life, the slug as a whole was dead.
Conan was still slashing furiously when a voice made him whirl about.
It said:
"I've got you this time!"
It was Nestor, approaching sword in hand, with a bloodstained bandage around his head in place of his helmet. The Gunderman stopped at the sight of the slug. "Mitra! What is this?"
"It's the spook of Larsha," said Conan, speaking Zamorian with a barbarous accent "It chased me over half the city before I slew it." As Nestor stared incredulously, the Cimmerian continued: "What do you here? How many times must I kill you before you stay dead?"
"You shall see how dead I am," grated Nestor, bringing his sword up to guard.
"What happened to your soldiers?"
"Dead in that rock slide you rigged, as you soon shall be—"
"Look, you fool," said Conan, "why waste your strength on sword strokes, when there's more wealth here than the pair of us can carry away—if the tales are true? You are a good man of your hands; why not join me to raid the treasure of Larsha instead?"
"I must do my duty and avenge my men! Defend yourself, dog or a barbarian!"
"By Crom, I'll fight if you like!" growled Conan, bringing up his sword. "But think, man! If you go back to Shadizar, they'll crucify you for losing your command—even if you took my head with you, which I do not think you can do. If one tenth of the stories are true, you'll get more from your share of the loot than you'd earn in a hundred years as a mercenary captain."
Nestor had lowered his blade and stepped back. Now he stood mute, thinking deeply. Conan added: "Besides, you'll never make real warriors of these poltroons of Zamorians!"
The Gunderman sighed and sheathed his sword. "You are right, damn you. Until this venture is over, well fight back to back and go equal shares on the loot, eh?" He held out his hand.
"Done!" said Conan, sheathing likewise and clasping the other's hand.
"If we have to run for it and get separated, let's meet at the fountain of Ninus."
The royal palace of Larsha stood in the center of the city, in the midst of a broad plaza. It was the one structure that had not crumbled with age, and this for a simple reason. It was carved out of a single crag or hillock of rock that once broke the flatness of the plateau on which Larsha stood. So meticulous had been the construction of this building, however, that close inspection was needed to show that it was not an ordinary composite structure, lines engraved in the black, basaltic surface imitated the joints between building stones.
Treading softly, Conan and Nestor peered into the dark interior. "We shall need light," said Nestor. "I do not care to walk into another slug like that in the dark."
"I don't smell another slug," said Conan, "but the treasure might have another guardian."
