OK, I've already mentioned it but thought I'd mention it again. "The True Story of the Kelly Gang" is a great book. But, doing a slight bit of research, it's almost entirely true and Peter Carey had to make surprisingly little up. It was an damned interesting subject before he tackled it.
Now if you want to read more about Ned Kelly, Australian bushranger and folk hero, start here. If you'd like to read Ned as spoken by Ned read The Jerilderie Letter. Neither of which articles are as long as the book, but the facts and testimony are remarkably consistent.
Or just pick up the Peter Carey book.
