There is sometimes a feeling in crime fiction that good writing gets in the way of story. I have never felt that way. All you have is language. Why write beneath yourself? It's an act of respect for the reader as much as yourself.
As I get older I tend to rail against the world more and more.
I've been fascinated by the idea that evil is the absence of empathy.
I think people are confusing the right to write with the right to be published.
What is good for you creatively is usually bad commercially. You thrive financially by sticking to a series and not fiddling about too much. You do yourself harm by moving away from the series and the genre. By trying things not based in that particular mode of writing, you will just lose readers.
