Should be possible at some point. But since GPT is so general, I think you have to coax it a little first, to get in the "mood" to be an author, or at least to make it be consistent in its style. Perhaps retrain or feed it with crime novels from a particular author to better understand what constitues a GOOD story written in a certain style.
Sort of like the tricks people use to make ChatGPT write code. ChatGPT isn´t (wasn´t) willing to write code, you had to sort of get it to accept certain rules first, a sort of framework, but when that was done it could output code.
