Wordle Challenge #3 (Now with Hints!) Deadline = Sat. midnight

Wordle Challenge #3 is perhaps too difficult, though likely not for those immersed in the murky waters of French tradition.

*snark*

Still, I think that if you had an intro to French lit at university, this is easily within your reach. Here are two hints: Louis Malle directed the movie version; The book's first word is a neologism that is a phonetic transcription of that existential question -- D'où qu'il pue donc tant?

As usual, identify the author and his/her work. But for real bragging rights, tell us to what/whom the citation refers (that is: oatmeal? doggy doo? Spiro Agnew?).

Good luck! As with Wordle Challenge #2, this one will be withdrawn if not solved by Saturday, midnight.
