My audiobook was paid for. Too long ago to remember from whom. My first guess is audible (or audible.fr) but my mobile network is down for the moment so I can't access Audible or even the Audible index of works ("2" factor, really "3" factor, verification for Audible/Amazon depends on a phone call; as does iTunes, so I can't check to see if I bought it from Apple). Nor can I confirm whether I bought audio for all three books in this trilogy. The audiobook is (probably) buried in one of 5 or 6 portable hard drives. I'll look, but it could take a long while (I'm house-sitting for friends who are vacationing in, of all places, France; they are tied to a tour, else I would ask them to check FNAC for us).
Gallimard in Montreal carries the books but apparently not the audio. [I give the web address cause Gallimard can be a could source for French materials, though the shipping costs from Canada to the the USA can be unbelievably high.]
I do think it is possible that I bought a CD for this, so I tried to contact FNAC to check, but I am denied access (???). My VPN connects through the USA. I could connect through the Netherlands, and that might solve the connection issue, but I need my USA connection for other things at the moment.
Anyway, if you buy or if you borrow, I don't think you'll be disappointed by
Le grand cahier.
Thanks to Dave for the web resource.
Edit. I found the audiobook. It is in mp3 format, so probably not an Audible, but rather from a CD.
