I don't know if the speculation about a 25th volume in the article is really warranted. The article is worded like the referenced volume is extremely rare and little is known about it ("...from the rather scant information available about the book...") but this is simply not the case - the book is freely available from online stores. Also, the version of the article on French Wikipedia clearly considers "le secret du vieux" and "le vieux" as the same book, and doesn't even consider that they may be different - attributing the difference in title to just a typo. Everything I've seen about the book and its synopsis etc suggest that they are the same book and there is no "25th volume". Kidburla (talk) 20:53, 25 May 2021 (UTC)[reply]
