I mostly skimmed it. It’s entirely feasible that the author buried a confession about getting away with manslaughter or whatever that I missed somewhere in a few sentences in the middle of that novella though. It does begin with several paragraphs essentially telling you not to read the post and has a lot of completely unnecessary exposition (for example the section on Luddites)

Edit: I want to point out that I went over the post with my own eyeballs and brain
