It was the first sign of fear he had ever seen from her.

The act was a desperate one, a sign of deep fear.

She knew that he was watching her for signs of fear.

They turned back, and stared at him, showing no sign of fear.

She looked for any sign of fear in his eyes, but saw none.

He stares hard into my eyes looking, I think, for a sign of fear.

But the man still neither spoke nor showed any sign of fear.

He didn't break eye contact or show any sign of fear.

There was no panic in him, nor yet any sign of fear.

It was the first sign of physical fear she had seen in him.
