Well of course, that's the bottom line. If you enjoy something you hope it's fairly accurate, you trust the author, who is taking you on such an enjoyable ride, is correct, because you are probably going to repeat something in the book sometime, like "did you know that..." Or "I read that..." If what's being repeated turns out NOT to be true, it certainly causes one to have egg on one's face, like the movie Gladiator with Commodus dying in the amphitheater. Happily that movie has page after page of the errors noted, books often do not.
I always wonder why, if they have all these facts, they have resorted to a novel form instead of writing a history. And this is the main reason that I have so many problems reading historical fiction.
I've got a copy of it now, I don't see anything at all about any sort of credentials of the author. I'm also reading Alexander McCall Smith who puts a lot of Latin in his books, even down to a drawing of Cave Canem, and I'm also reading Micro by the late Michael Crichton, finished by another author, and it's also full of Latin. Somehow Latin seems to be coming back which is very exciting to me, and OH did you see the news yesterday?
Hang on...
