For the past few months I have not been able to come up with an ending to my story that I am satisfied with and feels holds together well enough. I know what I want to happen, but I cannot figure out HOW it happens at all. I have posted a few different outcome ideas in the past few months, but none of them really held together I feel. Basically it's a thriller where the cops are on the track of a serial killer type villain. However, I cannot think of a legal method for the police to be able to catch the villain. Every scenario I come up with, would not be admissible in court, for various legal reasons. However, this is the problem as I would like to keep the plot simple, but the law is so convoluted that trying to apply it causes the story to become more and more convoluted, and I still haven't found a way the law can work to bust the killer. Another one of the problems is, is that all of the killers crimes are committed indoors, and she always has a reason to be clean up the crime scene after. There is no reason to leave any evidence behind and any evidence that would be left behind are in a private place, that would be almost impossible to search without legal grounds, and the police cannot get any, since all they would have is theories. There is no evidence to get cause for a warrant since all the evidence is inside there, so I keep arriving at paradoxes, no matter how I have tried to plot it, for the past few months. Those are just a couple of examples, as their are many other convoluted laws which get in the way of catching the villain as well. One writer suggested that I should just let the villain win, as the law is just not written to catch crooks of this sort, and I should stop forcing it. But do you think I should, or am I doing something wrong in my plotting that I am not seeing?
