After a while, they bumped gently against something that had to be a wall, it was so big, though at first she wasn't sure it was a wall. They moved along it for a time, then came to the end of it and were moving in the right direction again.

They seemed to be in a passage now, a rather narrow one. They touched walls and ceiling from time to time. She thought they were moving downward.

There was a picture in front of her. She realized suddenly that she had been watching it for some time. But it wasn't until this moment that she became really aware of it.

The beast was big, strong and angry. It bellowed and screamed, shaking and covered with foam. She couldn't see it too clearly, but she had the impression of mad, staring eyes and a terrible lust to crush and destroy.

But something was holding it. Something held it quietly and firmly, for all its plunging. It reared once more now, a gross, lumbering hugeness, and came crashing down to its knees. Then it went over on its side.

The suit's beams flashed on. Trigger squeezed her eyes tight shut, blinded by the light that flashed back from black walls all around. Then her fingers remembered the right drill and dimmed the lights. She opened her eyes again and stared for a long moment at the great gray mummy-shape before one of the black walls.

"Repulsive?" she asked in her mind.

Repulsive didn't answer. The suit hung quietly in the huge black chamber. She didn't remember having stopped it. She turned it now slowly. There were eight or nine passages leading out of here, through walls, ceiling, floor.

"Repulsive!" she cried plaintively.

Silence.
