This is Delphine, from France. I am a scholar and a chief editor for a French publisher (Zulma). I am working on bodies in detective fiction. Don't hesitate to contact me if you have ideas on the subject.
Other than that, I have the impression that a lot of writers start writing detective fiction to counterbalance a frustration. I mean your husband is a jerk. Well, instead of killing him for real, which mich land you in prison, you kill him in a novel (and then, when you are feeling better, with the profit of your novel, you get yourself a good divorce lawyer :-))) What is your point of view?
