This is a good one I’ve known about for a while. He’s the kind of guy who could build a batcave for Batman.
I find this guys story fascinating, not sure how accurate they are but the floor plans of his ‘murder castle’ are really interesting
To me he kinda sounds like a guy who would build a batcave for Joker, tbh.
The Devil in the white city is a great book, but don’t go in it expecting a book solely about a serial killer. It’s more about the concurrent stories of the killer and the world’s fair.
