Bonhoeffer: Pastor, Martyr, Prophet, Spy by Eric Metaxas. From Amazon: "After discovering the fire of true faith in a Harlem church, Bonhoeffer returned to Germany and became one of the first to speak out against Hitler. As a double agent, he joined the plot to assassinate the Fuhrer and was hanged in Flossenberg concentration camp at age 39. ince his death, Bonhoeffer has grown to be one of the most fascinating, complex figures of the 20th century."
