Joanne Froggatt, who stole the hearts of millions of viewers as Anna, the loving and resilient lady’s maid on Downton Abbey, stars in a totally different role in this spine-tingling drama. Dispensing death from the spout of a warm teapot, Froggatt plays the notorious Victorian poisoner Mary Ann Cotton, Britain’s first female serial killer.

Born in North East England in 1832, a child of the coal fields, Mary Ann Cotton grew up in poverty with the dream of escaping the hard life of a miner’s family, a goal she came tantalizingly close to achieving. Her chosen means were her good looks, sexual allure, and the dirty secret of nineteenth-century suspicious deaths: arsenic, which is tasteless and easily disguised in a cup of tea.

For authorities, the problem was that arsenic poisoning, if done skillfully, mimicked the symptoms of two of the major public health scourges of the day: typhoid fever and cholera. The passing of a child or husband after a week of severe stomach pains, convulsions, and other portents of disease was all too common—and even less surprising when several members of the same household succumbed.

Mary Ann did tempt fate by taking out a modest insurance policy on her intended victims, whenever possible, but she inadvertently hit on the major success strategies of a serial killer: keep moving, be charming, and exude self-confidence. And along with others in this line of criminality, her body count can never be certain; the current best estimate is at least thirteen, ranking her far above her Victorian male counterpart, Jack the Ripper.

Female serial killers are so rare that criminologists continue to debate what makes them tick. Is it a thirst for power, a desire for material gain, or a sadistic delight in undermining gender stereotypes when they ask, “Why don’t I make you a nice cup of tea?”
