There was the hint of a smile on her face.

There was even a hint of a smile on his face.

She'd heard, and now gave what looked like the hint of a smile.

There was just a hint of a smile in his eyes.

A hint of a smile as she said it again.

The first officer looked at me with just a hint of a smile.

Maybe a hint of a smile tried to break through.

He could not see the hint of a smile on his face.

He looked then at me, with a hint of a smile.

Yet she was all business, not a hint of a smile.
