Crime fiction is loose definition for something that can be the traditional story or a gritty and gorey novel featuring serial killers.
This is an intersting read but somehow if felt rushed and it seems more oriented to list and discuss thrillers than other type of crime of stories. A cozy or a traditional mystery are crime story. MC Beaton or Louise Penny sell tons of books but they're not in this list.
The theory that women want gore seemed a bit farfetched to me, I like true crime but I'm not a fan of too much gore and I'd like to know how large the statistical pool is.
Another note: I don't think it's ok to spoil the solution of a crime story.
I had high expectations, learn something new and was a bit disappointed
