" Grant paused in the act of turning the thing over, to consider the face a moment longer. A judge? A soldier? A prince? Someone used to great responsibility, and responsible in his authority. Someone too-conscientious. A worrier; perhaps a perfectionist. A man at ease in a large design, but anxious over details. A candidate for gastric ulcer. Someone, too, who had suffered ill-health as a child. He had that incommunicable, that indescribable look that childhood suffering leaves behind it; less positive than the look on a cripple’s face, but as inescapable. This the artist had both understood and translated into terms of paint. The slight fullness of the lower eyelid, like a child that has slept too heavily; the texture of the skin; the old-man look in a young face.

On the back was printed: Richard the Third. From the portrait in the National Portrait Gallery. Artist Unknown. "
