It has a sacred angel in this surprising plot (and not a holy angel) and also a brake fluid reservoir, certainly, but there is also and especially a young girls' boarding school to the old, run by nuns and where one assassinates lot (people dropping like flies!) there are also a white priest who told progressive and future black bishop to himself -As far more rigorous than everyone thinks. There are also fabulous and languid landscapes of Anjou and Touraine and their propensity to advance exponentially, in this very pretty countryside but if "deep", the most obtuse of the bourgeoisies (at Chabrol) and any provided it (usually go together) most active theologies.
This original and very funny thriller is finally a simple and fairly short novel about black also very dark dangers of fanatical religion and sisters: the rigors of very strange theology ...
It's a little old book, but if you manage to get it I swear you'll pay -for not very research- a damn good slice of fun! (Lol)
