Choosing the final killer for my Serial Killer Supper series - at least for October; frankly, I'm having too much fun to stop forever - was no easy task. I don't know if you've noticed, but there is no shortage of crazed murderers in this world. That said, how could I resist featuring Herman Webster Mudgett, aka Dr. Henry Howard Holmes aka H.H. Holmes, the man billed as "America's First Serial Killer?"
