The Toll is Nancy Simpson's investigative true-crime series, rooted in cases from Springfield, Missouri, and the wider Ozarks. Simpson introduces herself as an award-winning journalist who has spent decades on stories in the region, and the credits list her as creator, investigator, host and audio producer. The title is the thesis. Each case is weighed by what it does to the people left around it: a daughter, a sister, a neighbor, a family that stops speaking. Season 1, The Path Back Home, concerns Shirley Jane Rose, a nine-year-old abducted and murdered in Springfield in 1975, whose body was found two months later in a shallow grave; Simpson notes the girl was her friend's cousin. Season 2, Poison • Control, is the sprawling one. It centers on Jeanne, a Mormon mother of four investigated by the FBI over suspected poisonings, and on her daughter Jeanette, whose attempts to warn relatives left her estranged from them. Salt shakers and Easter candy sit at the center of the story, alongside a string of husbands and relatives who fell ill. What sets the season apart is its paper trail. Simpson reads Jeanne's own writings and years of email between mother and daughter, pausing on word choices that do not quite fit, such as 'co-operate' where 'cooperate' would do. She files a records request with an Iowa police department, hires a private investigator to trace an old car, and quotes obituaries, a father's journal and Websleuths posts. She also goes back to places. In one episode she and Jeanette stand in a Holt Summit basement where Jeanette believes she saw something as a child that she has carried for decades. The numbered chapters build on one another, and 'Monsters' presents itself as the episode that pulls the pieces together. Simpson closes the season saying she has a timeline of nearly two hundred pages packaged and ready for investigators. Bonus episodes extend the story, with Jeanette speaking in her own voice, accounts from extended family, and 'Trust Issues', in which Simpson and her friend Emily Wilson compare other poisoning cases, among them Nanny Doss. Spotlight Series installments widen the map: 'Hearts for Gloria' concerns Gloria Jean Barnes, found at a Springfield truck stop in 1997, while 'Unsettled' follows the disappearance of bartender Rene Williams in Ava. 'My Mom Married A Murderer' takes up a 1970s Ozarks killing with a direct link to Simpson's own family. The show also steps onto more familiar ground with 'Main Character: A Gypsy Rose Blanchard Story', built around a neighbor's memories, in which Simpson argues the public story does not add up. Her narration is direct and personal, and she does not hide her opinions.
