Not too long ago I watched Valkyrie, a depiction of the amazing true story behind an attempted assassination of Adolf Hitler. See it yourself. It's an incredible piece of history that I previously knew little about, and I am definitely intrigued to find out more. I am especially compelled by the moral conflict that faced the conspirators: is it right to commit one sin (the murder of a tyrant) that many more sins might not be committed? It's a challenging one.
What I only discovered just today, however, is that the pastor and theologian Dietrich Bonhoeffer was also implicated in the plot to assassinate Hitler. It's fired me with a desire to learn more about this great man of God. I've had his Cost of Discipleship in my to-read pile for a while now, but I'd love to read a really good biography about him first. Any recommendations?
