Letters from Belloc

I wasn't aware of the book "Letters from Hilaire Belloc", edited by his early biographer Robert Speaight, until today. Are there any H.B. fans reading this that have read his letters? John DeJak recently posted one of Hilaire's letters to Chesterton. If his other letters are only a portion as good as this one, then Speaight's book would be edifying to read.
