Henri Désiré Landru was a French serial killer, nicknamed the Bluebeard of Gambais, who killed at least seven women in the village of Gambais between December 1915 and January 1919. Landru also killed at least three other women, plus a young man, at a house he rented from December 1914 to August 1915 in the town of Vernouillet, 35 km northwest of Paris. The true number of Landru's victims, whose remains were never found, was almost certainly higher.
