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
