One look at those eyes and she had known he was a dangerous man.

One look at me, and everyone will know that something is wrong.

One look at her, and you knew she was up to no good.

One look at his face and she knew not to say anything.

One look at the size of the boot, and I knew he wasn't making them for himself.

One look at her and they all knew how to whistle.

One look at the soldier and he knew things had changed.

One look at her face and he knew something was wrong.

"One look and I knew the whole story," she would tell friends years later.

The look in her eyes that said she knew something you didn't.
