I have killed several people (some brutally, others calmly) and yet I currently languish in jail for a murder I did not commit. When I think about what I actually did, I feel somewhat sad that nobody will ever know about the complex operation that I undertook. Getting away with it is highly preferable, of course, but perhaps when I’m long gone, someone will open an old safe and find this confession. The public would reel. After all, almost nobody else in the world can possibly understand how someone, by the tender age of 28, can have calmly killed six members of her family. And then happily got on with the rest of her life, never to regret a thing.
