The giant leaped out before his followers. “Where is Lembken?” he roared. “Where are the men?”

The giant clutched at a cringing negro boy and pulled him from his knees. “Where is he?” he shouted.

The boy was tongue-tied with fear. But a girl stepped forth bravely. “That way!” she said, pointing toward a door.

The mob whirled through in a torrent, following the Assyrian-bearded giant. I heard their shouts grow fainter. The women bolted, scattering through the dismantled rooms, seeking some other refuge. But one of them stopped and then came toward me quickly.

“She lied! He is there,” she whispered, pointing toward a wall. “Kill him, but whisper my name in his ear before he dies.”

I looked at the girl and recognized Coral, the maid who had supplanted Amaranth. I turned quickly toward the wall, and my eyes discovered the hidden door, flush with the wall. I burst it open and ran through.

I raced along a winding passage, hearing the mob’s cries far away as they ran on the false scent they had taken up. I emerged suddenly upon a little platform fronting a part of the crystal wall that was still standing in the rear of the Palace. The mob had not yet found the approaches to this secret refuge.

A glass gateway within the wall stood open, and outside, at rest in the air, I saw the dark airplane, with Hancock at the wheel. And at the gate, hesitating to set his feet upon the narrow plank that led to safety, was Lembken. His arms were filled with bundles, and on his shoulder a monkey perched, mouthing and gibbering. At his side kneeled a young girl, with hands clasped, urging Lembken to flight.

The old man heard me and turned around. I saw Hancock start forward, raise a Ray rod, and aim it at me. But Lembken stood in the way, and he could not fire.
