What to read after City of Endless Night?

When but a child of seven my uncle placed me in a private school in which one of the so-called redeemed sub-sailors was a teacher of the German language. As I look back now, in the light of my present knowledge, I better comprehend the docile humility and carefully nurtured ignorance of this man. In his class rooms he used as a text a description of German life, taken from the captured submarine. From this book he had secured his own conception of a civilization of which he really knew practically nothing. I recall how we used to ask Herr Meineke if he had actually seen those strange things of which he taught us. To this he always made answer, "The book is official, man's observation errs."
