What about Here I Stand: A Life of Martin Luther?
I read it 35 years ago, and only remember it vaguely. From the Amazon reviews, I assume it has a Protestant slant, but that doesn’t mean a book can’t give more than one side of a dispute.
One interesting quote from a review: “Bainton quotes Luther: “Faith is a living, restless thing. It cannot be inoperative. We are not saved by works; but if there be no works, there must be something amiss with faith.”
Another that sounds interesting is Luther: Man Between God and the Devil.

Good night, all!
Thanks thanks.
