Fatherland, by Robert Harris, a 1992 novel of alternate history conceived as: "What might have happened if the Nazis won World War II?" Set in 1964 Berlin, all the novel's characters are sharply drawn and passionately motivated in decidedly political directions.
The author has done his research and knows the Nazi world inside out, sticking with a number of actual high-ranking Nazis such as Reinhard Heydrich and Wilhelm Stuckart imaginatively projected into his fictional Germany. Other Nazis in the novel are consistent with those who followed their Führer back in the day. The novelist's language is as crisp as a Nazi goosestep, making for one fast-paced page-turner.
Hitler still in power in the 1960s. Once this book has been read, it cannot be un-read - or un-heard, if you listen to the BBC radio play:
