I am really hoping that someone will join me in my complete infatuation with Mr.March, Evan Peters' delightfully evil character on American Horror Story: Hotel . The Vincent Price voice? The thin little creep-stache? The suspenders? I'm simultaneously into it and completely disturbed by it at the same time. Unfortunately, the real life inspiration behind Evan's character can't be pacified by television magic, he was a flesh and blood monster straight from the pits of hell. So who was the man who inspired such a terrifying fictional portrayal? According to showrunner Ryan Murphy, Mr.March is based on prolific serial killer H.H. Holmes. Trust me, you didn't want to know this guy.
