Bestselling true crime author M. William Phelps comes onto the podcast to tell us the story of Amy Archer Gilligan, a turn-of-the-century serial killer who disguised her sociopathic tendencies beneath a kind, neighborly facade. Her lemonade was laced with arsenic, and her convalescent home was not a place where anyone could get better. Also discussed: hot tub horrors, female criminals’ skyrocketing brutality (eek), and an amazing undercover lady cop named Zola.
