I just wanted to point out that Olivia was Wolfe's mother's middle name. I seem to recall that he mentioned in an interview that she played a large part in his love of reading as a child. Your suggestion that avocations are important to finding one's real humanity really resonated with me, and I wonder if Wolfe is sort of thanking his mother for her help. I can't help wondering if she ever read it, and what she might have thought.
If memory serves, Wolfe also said that Peace was the "most autobiographical" of his books.
