Born in Brittany, France, in 1803, Helene once complained, "Wherever I go, people died." Sure they did. Because she enjoyed poisoning them. As a teenager, as she started her career as a domestic, she also started experimenting with poison. Eventually she wiped out the family of seven for whom she was working. Most of her subsequent employers suffered the same fate. Curiously, no one suspected her of any wrongdoing because of her pious demeanor.

In 1831, after killing one too many familioes and fearing arrest, she joined a nunnery and took her vows. There she was suspected of offing several sisters before renouncing God and returning to her job as a domestic. As before, people started dying in her wake. Strangely she kept getting hired for new jobs.
She laid off the arsenic between 1841 to 1849 but then started dipping into it again. After two deaths in the household where she was working police started suspecting her after her overtly defensive manner during a routine questioning. Furthermore, traces of arsenic were found in the bodies of the most recent victims as well as many of her former employers. However, Helene never admitted her guilt, In 1851 she was guillotined just the same for her wave of terror. [ReadOn]
