The light from the central room was blocked by a spectral shape.

Reggie would have shaken, had he seen that spectral shape.

Then, like a spectral shape from the darkness, came a long white hand.

It rose toward the wall, and developed into a tall, spectral shape of human proportions.

Once more he was the spectral shape that Tyrell had first seen.

A long, spectral shape of blackness stretched across the floor.

Just within the door stood a spectral shape in black.

From then on, the skulking men were followed by a spectral shape that they didn't know was near.

He was gazing upon a spectral shape that might have come from some corridor of space!

I looked about, half expecting to see some spectral shape coming up the stairs.
