You also usually cite what you know. Maybe OP has not read the book.
replyWell, I've read a translation of the book. If that scene was present, it made no impression.
replyIt's not very comedic in the book. You can see for yourself: it is the entirety of chapter 47, here: https://gutenberg.org/cache/epub/1257/pg1257-images.html#cha... .
(Interestingly, I would have said that the translation I read came from Project Gutenberg, but it wasn't the one I just linked and no other is currently available there. Does Project Gutenberg take down existing versions of out-of-copyright books sometimes??)
If the book is out of copyright is the translation also out of copyright?
replyEdit: apparently not. So Gutenberg is hosting whatever they legally can, which is older translations.
There are multiple older translations, but Project Gutenberg only has one at the moment. I'm conjecturing that they used to have a different one (also out of copyright; that's their whole thing), but have taken it down for unclear reasons.
replyIt's also possible that I found a free translation of The Three Musketeers somewhere else, or that I read the same version PG has now and have misidentified it as being different.
