By reading La curée, I suspect that Angele, was in fact poisoned by Sidonie Rougon, by means of the “tizanes” which she gives her sister in low.
What do you think about?
Haha!
This forum is actually about the Zola software: https://www.getzola.org/
It’s a reference to the author, and to another similar older software named Hugo (also a reference to a French author)
I don’t know if you know this and joking or if the post was serious 
Anyway I didn’t read that one, but I can’t recommend more Germinal, now that we talk about Émile Zola!
