"Everywhere the Servants grew in popularity, there were murders and arson. Opponents of the Servants died. Minorities of every kind were persecuted, particularly the First People and followers of the major heresies. Even orthodox temples whose haruspices did not agree that fortune favored the Servants were burned to the ground.
Neither harassment, bearings, murder, arson, or rape was properly investigated when done by, or in the name of, the Servants. Or if they were, matters never successfully came to trial, in either State or Imperial courts. Local police left the Servants to their own devices."
— Garth Nix: Across the wall
So Garth Nix has a handful of characters who appear in his work that are pretty obviously based on Hitler. But it's interesting reading them in the US in 2025, because they feel almost prescient, in the small details. This story was published originally in 2003.
I think it's quite interesting to get a non-American perspective on the early Nazi regime; you can read posts about how American education leaves so much out as much as you want, but really seeing - even translated twice through the lens of fiction - a non-American-educated stance is very informative.
