Yes, in English - sorry, I should have specified.
Colin, I am not a Protestant . . . but, I took a look at our library catalogue and then google-searched this: "Luther: A Guide for the Perplexed" by David M Whitford. It’s publication date is 2011 and publisher T&T Clark. I don’t know if it meets your needs as it is being catalogued here so I cannot access it quickly.
I hear that series is a good one, the Guide to the Perplexed (a series title inspired by Moses Maimonides' famous work, no doubt). But I am looking for something quite comprehensive. I have read other biographies on him, I just want to know what the leading current one is.
This is quite an old post I realize, and I've never read your blog unfortunately, but if you are still interested, "Luther: Man between God and the Devil" by Heiko Oberman is probably the best biography out there. I'm a protestant seminarian and Oberman is actually a Catholic, but an amazing Luther scholar. I loved this book -- not written as a typical biography, but wonderful.
I am surprised no one answered you over these few years with the standard bio of Martin Luther: Roland Bainton's classic, Here I Stand: A Life of Martin Luther. Very readable, excellent scholarship, and balanced.
