The shadow of a cold smile flashed across his face.
The Shadow was flashing a green spot to someone farther back.
The Shadow gave no visible sign; yet through his brain was flashing the full thought of the future.
The Shadow flashed the token that he had acquired the night before.
Turning about, The Shadow flashed a light along the ground.
A shadow flashed over him, and he glanced up.
When they reached the street, The Shadow flashed a tiny green light that the others did not see.
A shadow flashed blue as a kingfisher dove from a rock.
A shadow flashed across the screen, they heard a dull "Smack!"
Suddenly a black shadow flashed across the prince's vision.
