In ghastly, soul-shaking apprehension of the utterly alien, Ennis knew that the yellow circles were _eyes_--that that hell-spawned city of another universe was _living_--that its unfamiliar life was single yet multiple, that its lurid eyes looked now through the Door! Out from the insane living metropolis glided pseudopods of its green substance, glided toward the Door. Ennis saw that in the end of each pseudopod was one of the lurid eyes. He saw those eyed pseudopods come questing through the Door, onto the dais. The yellow eyes of light seemed fixed on the row of stiff victims, and the pseudopods glided toward them. Through the open door was beating wave on wave of unfamiliar, tingling forces that Ennis felt even through the protective robe. The hooded multitude bent in awe as the green pseudopods glided toward the victims faster, with avid eagerness. Ennis saw them reaching for the prisoners, for Ruth, and he made a tremendous mental effort to break the spell that froze him. In that moment pistol-shots crashed across the cavern and a stream of bullets smashed the pulsing web of wires! The Door began instantly to close. Darkness crept back around the edges of the mighty oval. As though alarmed, the lurid-eyed pseudopods of that hell-city recoiled from the victims, back through the dwindling Door. And as the Door dwindled, the light in the cavern was failing. "Ruth!" yelled Ennis madly, and sprang forward and grasped her, his pistol leaping into his other hand. "Ennis--quick!" shouted Campbell's voice across the cavern. The Door dwindled away altogether; the great oval facet was completely black. The light was fast dying too. The chief priest sprang madly toward Ennis, and as he did so, the hooded hordes of the Brotherhood recovered from their paralysis of horror and surged madly toward the dais. "The Door is closed! Death to the blasphemers!" cried the chief priest as he plunged forward. "Death to the blasphemers!" shrieked the crazed horde below. Ennis' pistol roared and the chief priest went down. The light in the cavern died completely at that moment. In the dark a torrent of bodies catapulted against Ennis, screaming vengeance. He struck out with his pistol-barrel in the mad mêlée, holding Ruth's stiff form close with his other hand. He heard the other drugged, helpless victims crushed down and trampled under foot by the surging horde of vengeance-mad members. * * * * * Clinging to the girl, Ennis fought like a madman through a darkness in which none could distinguish friend or foe, toward the door at the side from which Campbell had fired. He smashed down the pistol-barrel on all before him, as hands sought to grab him in the dark. He knew sickeningly that he was lost in the combat, with no sense of the direction of the door. Then a voice roared loud across the wild din, "Ennis, this way! This way, Ennis!" yelled Inspector Campbell, again and again.
