From the direction of the gate came a low easy-moving shape.

A low shape on the floor would mean less to him.

Again I saw the thing, a long low shadowy shape.

He could make out a low, heavy shape ahead on the left-a body?

He squinted, trying to identify the low, broad shape moving their way.

Soon, within seconds, he would see the low shape ahead of him.

Darker shapes, low to the ground, seemed to be running after the people and among them.

About halfway down the hill he saw what the low dark shapes were.

Six long low shapes darted from the water, all at once and wide apart.

The low black shapes of military hovercraft surrounded the building.
