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.
