Henri Désiré Landru was a French serial killer, nicknamed the Bluebeard of Gambais and a prolific marriage fraudster. He is confirmed to have murdered at least ten women and the teenage son of his first victim, primarily targeting lonely war widows whom he met through newspaper advertisements, seduced, defrauded of their assets, and then killed, disposing of their bodies by burning them in his stove. He committed these crimes between December 1914 and January 1919, first at a house in Vernouillet and later at an isolated villa in Gambais, near Paris. The true number of Landru's victims remains unknown, as police traced correspondence with 283 women, 72 of whom were never found. He is considered one of France's most famous and notorious murderers, whose investigation and trial became a media sensation in the aftermath of World War I. His case inspired Charlie Chaplin's film Monsieur Verdoux.
