A friend recommended Colm Toibin's "The Master" about Henry James and I read it while in Italy a couple of months ago, so that was fun; I am 2/3 through his "The Magician" about Thomas Mann and greatly enjoying it; Toibin, who is gay, has a way of expressing each author's interior head space (both James and Mann were attracted to men); here's a link to an article about him and his technique in the September 21, 2021, issue of The New Yorker: https://www.newyorker.com/magazine/2021/09/20/how-colm-toibin-burrowed-inside-thomas-manns-head
