Barba Azul / Bluebeard

The tale tells the story of a violent nobleman who has the habit of murdering his wives and the attempts of one wife to avoid the fate of her predecessors. Gilles de Rais, a 15th-century aristocrat and prolific serial killer, has been suggested as the source for the character of Bluebeard, as has Conomor the Accursed, an early Breton king.
