disappointed after "Married Dress"

Classic detective, very well structured, very well written (best wedding dress for sure), original plot, bluffing player in the last part, which is rare, mostly the late novels
is sloppy here ... this is not the case, quite the contrary,

Commissioner searched and friendly endearing supporting characters.
I have often thought of Fred Vargas, although the style of Lemaître is not as "literary", there is a commitment of the author for his characters and a taste for complex searched and intrigues.
J "come to my flat and it is huge!
I have not supported the reading of certain passages that I found a rawness and an unbearable violence. I had to jump whole pages I have flown over the corner of the eye to understand the power still on.
For me, it was an ordeal to go through this novel.
How to explain it?
I think my sensitivity has certainly evolved over the years, the quality of the book is not at all involved.
I can just say that certain passages to rethink that always give me the creeps!
Even a few days later!
Another observation I never read American Psycho, and I will never look the same look my nail scissors ...
However, I am not discouraged and reread this author (;-D with caution)
