H.H. Holmes, a 19th century serial killer in the US, opened a hotel which he had designed and built for himself specifically with murder in mind. It included soundproofed bedrooms, trap doors, walls lined with blowtorches and two incinerators.

“I was born with the devil in me. I could not help the fact that I was a murderer, no more than the poet can help the inspiration to sing — I was born with the ‘Evil One’ standing as my sponsor beside the bed where I was ushered into the world, and he has been with me since.”
