Many of Grimm's fairy tales have been lightened up for modern children. However, some of them are beyond any hope, and should only be read to children you hate.
All of Bluebeard's previous wives have died under sparsely detailed circumstances shrouded in mystery, although he has never been asked to produce either a body or an explanation, because police work at that time typically required crimes to be committed within a constable's field of vision. Somehow, Bluebeard convinces another woman to marry him and takes her back to his castle before immediately announcing that he has to go away for a while, presumably holding a shopping list reading "lotion, catgut, lipstick, 'Goodbye Horses.'"
Bluebeard, the first and least creepy pickup artist.
As he leaves, Bluebeard stresses that she can go anywhere in the castle except the cellar. He then gives her the key to the cellar.
Of course she opens it, and inside she finds all of Bluebeard's missing wives hanging on hooks from the ceiling. Bluebeard returns instantly (he was probably waiting outside with his ear pressed to the door), declaring his intention to stabmurder her, but she is rescued at the last moment by her two brothers, who stabmurder Bluebeard instead.
Then they all move into his house. Because murder wasn't enough of a middle finger.
