Germans Against Hitler - July 20, 1944

Given all the films and books available about the 20th  of July 1944 attempted assassination of Hitler and coup, I find this book the most fascinating one, as it contains a meticulous collection of the most striking reports of investigations on the Reich from juridical, theological and military standpoints. It is an invaluable read to fully understand the German Resistance, its motives, and its historical significance.
