(The title of both series and book comes from the only one of the Zodiac’s ciphers to be partly solved: “man is the most dangerous animal of all,” a reference to the 1924 short story The Most Dangerous Game, about a man who hunts humans, by Richard Connell.) Stewart, a building maintenance business owner from Louisiana, came about the suspicion his birth father was the Zodiac killer incidentally, in reconnecting with his birth mother, then fervently: the series foregrounds the claims made in the book with Stewart’s compulsive, all-consuming obsession with finding out the truth about his family’s past.
That’s the focus of The Most Dangerous Animal of All, a four-part series investigating the 2014 bestselling book of the same name by Gary Stewart and journalist/true crime writer Susan Mustafa.
