Just read Alistair Duncan's The Norwood Author. It's a biography of Arthur Conan Doyle, covering the few years he spent living in Norwood. During this time he wrote several Sherlock Holmes stories including the notorious one where he kills off his hero.
I bought this one following reading an interview with the author on Helen Hunt's blog, and reading her review of the book on Bookersatz. A pleasant enough quick read, though I expect appeals more to diehard Sherlockians more than to me. I was hoping for a little more social history, I guess, as I'm fascinated by Victorian times. There were bits of it, but not enough to really grab me. Nice little book though, and well illustrated.
