Wolf Hall (Thomas Cromwell, #1) - Hilary Mantel

"But it is no use to justify yourself. It is no good to explain. It is weak to be anekdotal. It is wise to conceal the past even if there is nothing to conceal. A man´s power is in the half-light, in the half-seen movements of his hands and the unguessed-at expressions of his face. It is the abscence of facts that frightens people: the gap you open, into which they pour their fears, fantasies, desires."
