SOLVED. French Novel Re: Three Nannies Published 2018 or 2019. [s]

I'm looking for the title of a French novel which was translated into English in 2018 or 2019. All I can recall about the plot is that it involves three nannies and they are portrayed as mesmerizing sirens of sorts. I think it may be set in an earlier era, perhaps the 1940s or 1950s.

Could it be this one https://www.goodreads.com/book/show/7... ?

Thanks for the suggestion! I figured it out. It's not actually about nannies, but rather governesses: https://www.goodreads.com/book/show/3...
