This brought tears to my eyes and creeped me out -- EXCELLENT writing in a lot of ways. It was like rolling Ten Little Indians, Lord of the Flies, Downfall, and some real facts from both the disaster at Chernobyl up together ... also complete with a grasp of human nature and how irresponsible we sometimes show ourselves to be in terms of not wanting to get to the bottom of how lots of people beside ourselves are harmed and killed. Justice for the dead swamped out by the desire to move on with life... it is not just a fictional occurrence...
I used to read a bunch of mysteries, and so I did try to "solve" this, based on the clues at hand. It takes superior physical and emotional energy to just kill 26 people, especially when one considers necks snapped, throats slit, and suffocation. That eliminates the vast majority of women from consideration. It also takes about that same amount of emotional and intellectual energy to narrate the whole account in situ... and I also notice the narrator is throwing balls in the air to let off some excess nervous energy while others are drained and can barely eat. By contrast: it also requires conservation of energy when not at "work," and I notice the narrator coming from sitting and lying down a couple of times. The narrator is also perfectly acquainted with the design of every bunker, and all security measures. If I were investigating these crimes after the fact, I would consider the narrator my chief suspect.
