She looked like everyone’s grandmother. Soft-spoken. Smiling. Laughing at her own jokes.

But behind that laugh was a trail of bodies.

In this chilling episode of Among Monsters, host Myia Vale pulls back the curtain on Nannie Doss, better known as The Giggling Granny—one of America’s most unsettling female serial killers. Between the 1920s and the 1950s, Nannie quietly poisoned her way through husbands, children, relatives, and acquaintances, all while maintaining the image of a harmless, cheerful old woman.

This episode explores Nannie’s deeply troubled childhood, her obsession with romance novels, her warped view of love and marriage, and how she used arsenic and poison as tools of control. We examine the crimes she confessed to, the murders she was suspected of, and the eerie calm with which she discussed killing—often punctuated by nervous laughter that haunted investigators.

How does someone kill with a smile?

How did she evade suspicion for decades?

And what does her story reveal about the monsters who hide in plain sight?

This is not just the story of a killer—it’s a study of deception, domestic horror, and the terrifying reality that evil doesn’t always look monstrous.
