Stern got a glimpse of a circular row of stone posts, each about nine feet high--he saw not the complete circle, but enough of it to judge its diameter as some fifty feet. In the center stood a round and massive building, and from each post to that building stretched a metal rod perhaps twenty feet in length.
"Look! Look!" gasped Beatrice, and pointed.
Then, deadly pale, she hid her face in both her hands and crouched away, as though to blot the sight from her perception.
Each metal bar was sagging with a hideous load--a row of human skeletons, stark, fleshless, frightful in their ghastliness. All were headless. All, suspended by the cervical vertebrae, swayed lightly as the blue-green light glared on them with its weird, unearthly radiance.
Before either Stern or the girl had time even to struggle or so much as recover from the shock of this fell sight, they were both pushed roughly between two of the posts into the frightful circle.
Stern saw a door yawn black before them in the massive hut of stone.
Toward this the Folk of the Abyss were thrusting them.
"No, you don't, damn you!" he howled with sudden passion. "None o' that for us! Shoot, Beta! Shoot!"
But even as her hand jerked at the butt of the automatic, in its rawhide holster on her hip, an overmastering force flung them both forward into the foul dark of the round dungeon. A metal door clanged shut. Absolute darkness fell.
"My God!" cried Stern. "Beta! Where are you? Beta! Beta!"
But answer there was none. The girl had fainted.
