Thank you Bill, all very palatable points you bring up. Although I can see someone, maybe not Kneale but someone using a science fiction motif as a warning to the horror and the danger of the Nazi doctrine.Not that far-fetched for Kneale tackel that subject subliminally. Remember this is 1957 or when ever he wrote this,and the subject was still very taboo.Nobody was talking,no one was taking responaibility. I don't think this truth really had legs until the 70's when the TV mini series HOLOCAUST opened the flood gates.
