His face was like a law of nature
He knew that the days ahead would be difficult. There were questions to be faced and a plan of action to be prepared. He knew that he should think about it. He knew also that he would not think, because everything was clear to him already, because the plan had been set long ago, and because he wanted to laugh.

He did not laugh as his eyes stopped in awareness of the earth around him. His face was like a law of nature -- a thing one could not question, alter or implore. It had high cheekbones over gaunt, hollow cheeks; gray eyes, cold and steady; a contemptuous mouth, shut tight, the mouth of an executioner or a saint.
