creatures, saw them climb over the rail. Then the blackness of a dank and musty cabin enveloped him; and he was dropped with jarring force. His captors bulked black against the moonlit doorway, treading soundlessly, and were gone.

Cliff lay in rigid paralysis, every sense keenly alive, his mind striving to clutch a single spar of reason in this chaotic whirlpool of the incredible. This couldn't be! Soon he'd awaken to laugh at his absurd nightmare.... Yet it seemed horribly real.... It was real!

From the Ariel boiled a fearful bedlam. Screams of terror. Curses. Then other shadows loomed in the doorway, and Vilma, motionless and rigid, was dropped brutally beside him on the spongy floor.

Furiously Cliff struggled against the maddening restraint of paralysis. He couldn't lie here helpless! Vilma needed him! He'd—he'd have to do something. With an effort that studded his forehead with rounded drops of sweat and sent the blood throbbing through the distended veins of his neck, he sought to move. And like a cord snapping, his invisible bonds fell from him.

He was crouching over Vilma, rubbing her wrists, calling to her, when again he heard the silver horn of Corio. A low droning utterly unlike the note that had awakened the galley's crew, it drifted languidly along a channel of endless sleep. It seeped through the ear-drums, touching every nerve-tip with resistless lassitude. Doggedly Cliff fought against the sound, pressing his hands over his ears, gritting his teeth, holding his eyelids wide. Yet he felt his muscles weaken, began to relax, knew dimly that his mind, sodden with drowsiness, was creeping toward the pits of slumber—and the vibrant drone ended!

is head cleared rapidly, and he bent over Vilma. As he touched a limp arm, he knew she had passed from paralysis into a deep, quiet sleep. He shook her. It was useless. He listened, heard her steady breathing; and at that instant realized that the noises from the yacht had ceased.

Rising, he strode toward the square of chalky moonlight. A foot away he halted, fell back. He had heard a faint footfall, had seen an armor-clad figure climbing over the rail! With silent haste he flung himself down beside Vilma.

And there he lay while the crew of the galley carried his friends from the Ariel, all slumped in that unnatural sleep, and stretched them out on the floor of the black cabin. Unmoving, he watched through narrow lids till all save Corio had been carried aboard, and the drowned things had gone back to their places in the rowers' pits. Again the hollow voice of the drum began throbbing through the silence, and the oars creaked a faint accompaniment. He could feel the galley cleaving the oily sea.

On his feet, he peered through the doorway. The backs of the rowers rose and fell with stiff, mechanical rhythm. Beyond the galley's stern came the yacht, slinking along like a thief, only one dim light showing, her Diesel engines purring almost soundlessly.

He turned and bent over Vilma, still in thrall to that strange deep slumber. As he traced the delicate outlines of her lovely face, now so lifeless and pale, bitter wrath flared within him, wrath and hatred for Leon Corio. But as he thought of the ghastly undead things out there in the galley pit, thought of this water-soaked anachronism which had no right to be afloat, his skin crisped with a sense of foreboding, a fear of what was yet to come. He must do something!

Stepping over the still forms of his friends, he moved to the forward wall where a beam of radiance crept fearfully through a gap between two boards. His hands touched the hull—and he jerked them away. Rotten, clammy, like a decayed corpse, partly frozen. Crouching, he peered through.

Far ahead, a blotch of evil blackness squatted on the horizon, an island crouching low like a black beast ready to spring. Around it the moonlight seemed to dim, as though it were striving to hide some nameless horror. Interminably Cliff watched while the shadowed mass drew closer ... closer....

They were headed for a towering wall of black basalt; and as the galley neared it, Cliff saw that it bore striking resemblance to a gigantic human skull, its rounded surface broken by caves that the sea had carved into hollow eye-sockets and an empty nasal cavity. The rock wall ended high above the water; beneath it lay a gaping chasm of pitchy darkness. And the galley, drum silenced, oars at rest, slid under the ledge, into the mouth of the skull!

Just before total blackness fell, Cliff sprang to Vilma's side and raised her in his arms. If he hoped to do anything, he must do it now! He groped his way to the starboard bow and moved one hand along the dank timbers, searching. He found what he sought, a wide gap at the edge of a board. Gently lowering Vilma to the floor, he gripped the slimy wood with both hands and thrust outward mightily. A wide strip of decayed timber burst free. He dropped it into the sea and attacked the next board. In moments a wide irregular opening yawned in the galley's hull.

Leaning out, Cliff looked down. He could see nothing. Then suddenly a faint light appeared, and he heard the hum of the Ariel's motors as she entered the cave. The humming ceased instantly, but the faint light persisted.

Now he could see the blackness of waters, a rock wall beyond. He drew back—and a he did so, he heard movements on deck! At any moment the rowers might enter! He'd have to risk a drop into the water with Vilma—there was nothing else to do. If only she were conscious!

He stooped and raised her, holding her firmly with one arm. Gripping the hull with the other, he climbed through the opening, inhaled deeply, and dropped! A heart-stopping plunge—and cold water closed over them. Down, down—then they shot upward, reached the surface; and even as Cliff gulped a single gasping breath, something struck his skull a blinding, stunning blow! The oars!

With rapidly numbing arms and legs Cliff kicked and flailed the water, striving for land. Dimly he knew he no longer held Vilma; dimly he visioned her as were those ghastly undead; then his body scraped on something hard, and a blackness that was not physical blotted out consciousness.

2. The Dreadful Isle

ed-hot hammers pounding against his temples wakened Cliff Darrell. He opened his eyes to stare into total darkness crawling with mental monsters spawned by his pain-stabbed brain. He lay half immersed in shallow brine, his head resting on a jagged stone just above the surface. Struggling to his hands and knees, he shook his head from side to side, dumbly, like an animal in pain. Something had hit him—and now he was in water—and there was no light. What had happened? Where was Vilma?

Vilma! He groaned. He remembered now. They had dropped—and his head had struck something—and—and—maybe she was floating out there even now, dead eyes staring upward.

"Vilma!" he cried, his voice pleading. "Vilma!"

Only a mocking echo answered him. There was no other sound, not even the whisper of waves swishing among the rocks.

Cliff pressed his hands fiercely against his throbbing head. The pain had become a madness, matched only by the agony of his own helplessness. He felt his reason reeling; he fought an insane desire to fling himself shrieking into that silent expanse of water to search for Vilma; then with a tremendous physical effort he jarred himself back to sanity.

He staggered to his feet, groped stumblingly over the rocks away from the water. His hand touched a rock wall broken and pitted by the action of the sea; and he crept slowly inland, feeling his way
