More than thirty lean, gray forms now were waiting beyond the gate.

It wavered, shifting form to another man's, now gray and terrifying.

The light passed over him, struck a dozen gray bony forms.

Now all the grey forms were within the church.

Struggling gray forms on the floor, one or two.

Up ahead, forty yards away, he saw the vague gray forms of the elephants but there was something wrong with that too.

He hurried over to a gray form that lay in the underbrush.

The large, dark gray form within the tank seemed calmer now.

A grey form appeared at the outer edge of my vision.
