Here's one for the synchroncity file:
Empire of the Wheel presents data on The Zodiac Killer murders. One author, Steve Hodel, has presented a case that his father was both The Zodiac Killer and The Black Dahlia Killer (for which he was an actual suspect). One police witness in the Black Dahlia case was the victim's roommate at the time of her murder: Ann Toth. I first learned about the 'Cora Stanton' mystery from librarian Anne Toth Walker. Aleister Crowley, who figures in the first Empire of the Wheel book, wrote The Book of Thoth a tarot book sharing the title of a collection of texts with some themes resonant with the Empire of the Wheel mystery, and also features the obvious similarity between the names 'Thoth' and 'Toth'.
