Thank you @ubani1 for introducing me to the concept of Cyranoids. I thought you made it up and then found out it is actually a concept introduced by a bona fide research scientist. I was relieved that there was no murder at the end of the story.
It sounds to me as though our protagonist needs to lead a life with less secrets :)) I personally wouldn't be able to sleep at night worrying about such things.
I respect the way you devised a complex plot and worked it out so that it all falls together. Not easy to do in the space of a short story.
