tier above him, a tall, black-robed figure, naked head nodding slightly as he stared down. His whole attitude suggested mockery and malignity. Quick as a flash the Irakzai bent his bow and loosed, and the arrow streaked upward to strike full in the black-robed breast. The mocking smile did not alter. The Seer plucked out the missile and threw it back at the bowman, not as a weapon is hurled, but with a contemptuous gesture. The Irakzai dodged, instinctively throwing up his arm. His fingers closed on the revolving shaft.
Then he shrieked. In his hand the wooden shaft suddenly writhed. Its rigid outline became pliant, melting in his grasp. He tried to throw it from him, but it was too late. He held a living serpent in his naked hand, and already it had coiled about his wrist and its wicked wedge-shaped head darted at his muscular arm. He screamed again and his eyes became distended, his features purple. He went to his knees shaken by an awful convulsion, and then lay still.
The men inside had wheeled at his first cry. Conan took a swift stride toward the open doorway, and then halted short, baffled. To the men behind him it seemed that he strained against empty air. But though he could see nothing, there was a slick, smooth, hard surface under his hands, and he knew that a sheet of crystal had been let down in the doorway. Through it he saw the Irakzai lying motionless on the glassy gallery, an ordinary arrow sticking in his arm.
Conan lifted his knife and smote, and the watchers were dumfounded to see his blow checked apparently in midair, with the loud clang of steel that meets an unyielding substance. He wasted no more effort. He knew that not even the legendary tulwar of Amir Khutum could shatter that invisible curtain.
In a few words he explained the matter to Kerim Shah, and the Turanian shrugged his shoulders. "Well, if our exit is barred, we must find another. In the meanwhile our way lies forward, does it not?”
With a grunt the Cimmerian turned and strode across the chamber to the opposite door, with a feeling of treading on the threshold of doom. As he lifted his knife to shatter the door, it swung silently open as if of its own accord. He strode into a great hall, flanked with tall glassy columns. A hundred feet from the door began the broad jade-green steps of a stair that tapered toward the top like the side of a pyramid. What lay beyond that stair he could not tell. But between him and its shimmering foot stood a curious altar of gleaming black jade. Four great golden serpents twined their tails about this altar and reared their wedge-shaped heads in the air, facing the four quarters of the compass like the enchanted guardians of a fabled treasure. But on the altar, between the arching necks, stood only a crystal globe filled with a cloudy smoke-like substance, in which floated four golden pomegranates.
The sight stirred some dim recollection in his mind; then Conan heeded the altar no longer, for on the lower steps of the stair stood four black-robed figures. He had not seen them come. They were simply there, tall, gaunt, their vulture-heads nodding in unison, their feet and hands hidden by their flowing garments.
One lifted his arm and the sleeve fell away revealing his hand—and it was not a hand at all. Conan halted in mid-stride, compelled against his will. He had encountered a force differing subtly from Khemsa’s mesmerism, and he could not advance, though he felt it in his power
