The Shadow was plunging headlong to the end of a darkened trail.

Huge stones rolled down upon the hole into which The Shadow had plunged.

The center of the wall made a silent revolution; The Shadow plunged through to a space beyond.

On the chance that they meant something, The Shadow plunged through.

The Shadow plunged, too, but not to the ground.

Gone before the light could follow, The Shadow was plunging a hundred feet to the same river that had already claimed a dead man!

The Shadow swung onto the ladder and plunged below.

The Shadow and a group of mobsters had plunged down the front stairs.

The Shadow slipped from the green car and plunged into the dark forest of trees.

The Shadow plunged below into the bowels of the ship.
