“Follow me,” whispered Taurus, “keep behind me, as you value your life.”

Taking what looked like a copper tube from his girdle, the Nemedian dropped lightly to the sward inside the wall. Conan was close behind him, sword ready, but Taurus pushed him back, close to the wall, and showed no inclination to advance, himself. His whole attitude was of tense expectancy, and his gaze, like Conan’s, was fixed on the shadowy mass of shrubbery a few yards away. This shrubbery was shaken, although the breeze had died down. Then two great eyes blazed from the waving shadows, and behind them other sparks of fire glinted in the darkness.

“Lions!” muttered Conan.

“Aye. By day they are kept in subterranean caverns below the tower. That’s why there are no guards in this garden.”

Conan counted the eyes rapidly.

“Five in sight; maybe more back in the bushes. They’ll charge in a moment—”

“Be silent!” hissed Taurus, and he moved out from the wall, cautiously as if treading on razors, lifting the slender tube. Low rumblings rose from the shadows and the blazing eyes moved forward. Conan could sense the great slavering jaws, the tufted tails lashing tawny sides. The air grew tense—the Cimmerian gripped his sword, expecting the charge and the irresistible hurtling of giant bodies. Then Taurus brought the mouth of the tube to his lips and blew powerfully. A long jet of yellowish powder shot from the other end of the tube and billowed out instantly in a thick green-yellow cloud that settled over the shrubbery, blotting out the glaring eyes.

Taurus ran back hastily to the wall. Conan glared without understanding. The thick cloud hid the shrubbery, and from it no sound came.

“What is that mist?” the Cimmerian asked uneasily.

“Death!” hissed the Nemedian. “If a wind springs up and blows it back upon us, we must flee over the wall. But no, the wind is still, and now it is dissipating. Wait until it vanishes entirely. To breathe it is death.”

Presently only yellowish shreds hung ghostily in the air; then they were gone, and Taurus motioned his companion forward. They stole toward the bushes, and Conan gasped. Stretched out in the shadows lay five great tawny shapes, the fire of their grim eyes dimmed for ever. A sweetish cloying scent lingered in the atmosphere.

“They died without a sound!” muttered the Cimmerian. “Taurus, what was that powder?”

“It was made from the black lotus, whose blossoms wave in the lost jungles of Khitai, where only the yellow-skulled priests of Yun dwell. Those blossoms strike dead any who smell of them.”

Conan knelt beside the great forms, assuring himself that they were indeed beyond power of harm. He shook his head; the magic of the exotic lands was mysterious and terrible to the barbarians of the north.

“Why can you not slay the soldiers in the tower in the same way?” he asked.

“Because that was all the powder I possessed. The obtaining of it was a feat which in itself was enough to make me famous among the thieves of the world. I stole it out of a caravan bound for Stygia, and I lifted it, in its cloth-of-gold bag, out of the coils of the great serpent which guarded it, without awaking him. But come, in Bel’s name! Are we to waste the night in discussion?”

They glided through the shrubbery to the gleaming foot of the tower, and there, with a motion enjoining silence, Taurus unwound his knotted cord, on one end of which was a strong steel hook. Conan saw his plan, and asked no questions as the Nemedian gripped the line a short distance below the hook, and began to swing it about his head. Conan laid his ear to the smooth wall and listened, but could hear nothing. Evidently the soldiers within did not suspect the presence of intruders, who had made no more sound than the night wind blowing through the trees. But a strange nervousness was on the barbarian; perhaps it was the lion-smell which was over everything.

Taurus threw the line with a smooth, ripping motion of his mighty arm. The hook curved upward and inward in a peculiar manner, hard to describe, and vanished over the jeweled rim. It apparently caught firmly, for cautious jerking and then hard pulling did not result in any slipping or giving.

“Luck the first cast,” murmured Taurus. “I—”

It was Conan’s savage instinct which made him wheel suddenly; for the death that was upon them made no sound…
