Stark burst through.

      Stark continued his rush without stopping. He plunged headlong into the man before the point was clear of the scabbard, bore him over and down, and finished the man off with savage efficiency.

      He leaped to his feet, breathing hard, spitting blood out of his mouth, and looked around the control room. But the others had fled, obviously to raise the warning.

      The mechanism was simple. It was contained in a large black metal oblong about the size and shape of a coffin, equipped with grids and lenses and dials. It hummed softly to itself, but what its source of power was Stark did not know. Perhaps those same cosmic rays, harnessed to a different use.

      He closed what seemed to be a master switch, and the humming stopped, and the flickering light died out of the lenses. He picked up the slain guard's sword and carefully wrecked everything that was breakable. Then he went outside again.

      Treon was standing up, shaking his head. He smiled ruefully.

      "It seems that strength alone is not enough," he said. "One must have skill as well."

      "The barriers are down," said Stark. "The way is clear."

      Treon nodded, and went with him back into the sea. This time both carried shock-weapons taken from the guards—six in all, with Egil's. Total armament for war.

      As they forged swiftly through the red depths, Stark asked, "What of the people of Shuruun? How will they fight?"

      Treon answered, "Those of Malthor's breed will stand for the Lhari. They must, for all their hope is there. The others will wait, until they see which side is safest. They would rise against the Lhari if they dared, for we have brought them only fear in their lifetimes. But they will wait, and see."

      Stark nodded. He did not speak again.

      They passed over the brooding city, and Stark thought of Egil and of Malthor who were part of that silence now, drifting slowly through the empty streets where the little currents took them, wrapped in their shrouds of dim fire.

      He thought of Zareth sleeping in the hall of kings, and his eyes held a cold, cruel light.

      They swooped down over the slave barracks. Treon remained on watch outside. Stark went in, taking with him the extra weapons.

      The slaves still slept. Some of them dreamed, and moaned in their dreaming, and others might have been dead, with their hollow faces white as skulls.

      Slaves. One hundred and four, counting the women.

      Stark shouted out to them, and they woke, starting up on their pallets, their eyes full of terror. Then they saw who it was that called them, standing collarless and armed, and there was a great surging and a clamour that stilled as Stark shouted again, demanding silence. This time Helvi's voice echoed his. The tall barbarian had wakened from his drugged sleep.

      Stark told them, very briefly, all that happened.

      "You are freed from the collar," he said. "This day you can survive or die as men, and not slaves." He paused, then asked, "Who will go with me into Shuruun?"

      They answered with one voice, the voice of the Lost Ones, who saw the red pall of death begin to lift from over them. The Lost Ones, who had found hope again.

      Stark laughed. He was happy. He gave the extra weapons to Helvi and three others that he chose, and Helvi looked into his eyes and laughed too.

      Treon spoke from the open door. "They are coming!"

      * * * * *

      Stark gave Helvi quick instructions and darted out, taking with him one of the other men. With Treon, they hid among the shrubbery of the garden that was outside the hall, patterned and beautiful, swaying its lifeless brilliance in the lazy drifts of fire.

      The guards came. Twenty of them, tall armed men, to turn out the slaves for another period of labour, dragging the useless stones.

      And the hidden weapons spoke with their silent tongues.

      Eight of the guards fell inside the hall. Nine of them went down outside. Ten of the slaves died with blazing collars before the remaining three were overcome.

      Now there were twenty swords among ninety-four slaves, counting the women.

      They left the city and rose up over the dreaming forest, a flight of white ghosts with flames in their hair, coming back from the red dusk and the silence to find the light again.

      Light, and vengeance.

      The first pale glimmer of dawn was sifting through the clouds as they came up among the rocks below the castle of the Lhari. Stark left them and went like a shadow up the tumbled cliffs to where he had hidden his gun on the night he had first come to Shuruun. Nothing stirred. The fog lifted up from the sea like a vapour of blood, and the face of Venus was still dark. Only the high clouds were touched with pearl.

      Stark returned to the others. He gave one of his shock-weapons to a swamplander with a cold madness in his eyes. Then he spoke a few final words to Helvi and went back with Treon under the surface of the sea.

      Treon led the way. He went along the face of the submerged cliff, and presently he touched Stark's arm and pointed to where a round mouth opened in the rock.

      "It was made long ago," said Treon, "so that the Lhari and their slavers might come and go and not be seen. Come—and be very quiet."

      They swam into the tunnel mouth, and down the dark way that lay beyond, until the lift of the floor brought them out of the sea. Then they felt their way silently along, stopping now and again to listen.

      Surprise was their only hope. Treon had said that with the two of them they might succeed. More men would surely be discovered, and meet a swift end at the hands of the guards.

      Stark hoped Treon was right.

      They came to a blank wall of dressed stone. Treon leaned his weight against one side, and a great block swung slowly around on a central pivot. Guttering torchlight came through the crack. By it Stark could see that the room beyond was empty.

      They stepped through, and as they did so a servant in bright silks came yawning into the room with a fresh torch to replace the one that was dying.

      He stopped in mid-step, his eyes widening. He dropped the torch. His mouth opened to shape a scream, but no sound came, and Stark remembered that these servants were tongueless—to prevent them from telling what they saw or heard in the castle, Treon said.

      The man spun about and fled, down a long dim-lit hall. Stark ran him down without effort. He struck once with the barrel of his gun, and the man fell and was still.

      Treon came up. His face had a look almost of exaltation, a queer shining of the eyes that made Stark shiver. He led on, through a series of empty rooms, all sombre black, and they met no one else for a while.

      He stopped at last before a small door of burnished gold. He looked at Stark once, and nodded, and thrust the panels open and stepped through.

      XII

      They stood inside the vast echoing hall that stretched away into darkness until it seemed there was no end to it. The cluster of silver lamps burned as before, and within their circle of radiance the Lhari started up from their places and stared at the strangers who had come in through their private door.

      Cond, and Arel with her hands idle in her lap. Bor, pummelling the little dragon to make it hiss and snap, laughing at its impotence. Varra, stroking the winged creature on her wrist, testing with her white finger the sharpness of its beak. And the old woman, with a scrap of fat meat halfway to her mouth.

      They had stopped, frozen, in the midst of these actions. And Treon
