Writing fiction, letters to his family, fiancee, and friends and contending with his interrogator occupied Bonhoeffer during his first year in Tegel Prison. Of the incomplete drama, the novel fragment, and the short story, Bonhoeffer admitted to his friend and later biographer, Eberhard Bethge, "There is a good deal of autobiography mixed with it." This book discloses a great deal of Bonhoeffer's family context, social world, and cultural milieu. Events from his life are recounted in a way that embodies and illuminates his theology. Characters and situations that represent Nazi types and attitudes are a form of social criticism and help to explain Bonhoeffer's participation in the resistance movement and the plot to kill Adolf Hitler, for which he was hanged.
