But I don't think it spoils anything to note that Ceylon didn't become Sri Lanka until 1972 and that La Petit Trope should be Le Petit Trope. That's all so far. I guess the publisher didn't want to waste money on a copy editor.
Maybe, my beautiful, DarkLady, the copy-editors were too busy expunging the various DS names and places (other than that hidden "whoopsee") to make sure no one got sued by you-know-who, rather than looking at historical/literary accuracy. Screw up a country's or a title's name, there's nothing involved; bringing up something copyrightedcopyrightedcopyrightedcopyrighted (it's all copyrighted, don'tchyaknow), and there's cash involved. As someone with a degree in history, and has done a tad bit of copy-editing, the threats of lawyers showing up in smart business outfits and brief cases carries far more weight than accuracy.
