One night, three young men shoot the owners of a hunting lodge. The man who hired them claims he only asked them to do one thing: scare the people who were resisting him. How do you come to kill when you're barely twenty and there's no war going on?
Not less than 3 men and 40 animals were found dead on the Breton beaches. The identity of the killer is an open secret: green algae. Inès Léraud is still a young journalist when, driven by an ecological conscience, she decides to go to Brittany to investigate this phenomenon. Through her encounters with whistleblowers, scientists, farmers and politicians, she elucidates, not without difficulty, half a century of silence: samples that disappear in laboratories, bodies buried before being autopsied, influence games, pressure... Will the truth win?
The French government is asking Gustave Eiffel to design something spectacular for the 1889 Paris World Fair, but he simply wants to design the subway—until he crosses paths with a mysterious woman from his past.
In 1800, Brittany is on its knees, overwhelmed by the regime in place and by the omnipotent clergy. It founders in an economic slump without end in sight and, in the middle of all this, a young, suffering girl pushes back as best she can. She is known as the "Poisoning Angel," an isolated child, mistreated by life and rocked by morbid thoughts. She will become one of the world's most notorious serial killers and will sow death, perhaps merely to be looked at and loved.
