That's interesting. My question is that when I write, which I do quite enjoy, I can never bother writing anything that isn't part of the core purpose of the story, so my writing tends towards poetry and short stories (and isn't publishable quality anyway, lol). When you write a whole book do you have sort of core plot line for this book outline, then, say character development of characters plotlines that go across several books if you have a set of characters like Strike and Robin, then padding, red herrings etc?
The plotting of thrillers seems like it's fiendishly more complex to actually do than a reader might think?
