Sometimes, when Chapuys has finished digging up Walter’s bones and making his own life unfamiliar to him, he feels almost impelled to speak in defence of his father, his childhood. But it is no use to justify yourself. It is no good to explain. It is weak to be anecdotal. It is wise to conceal the past even if there is nothing to conceal.

It is the absence of facts that frightens people: the gap you open, into which they pour their fears, fantasies and desires.
