The Golden Egg (Dutch: Het Gouden Ei), published as The Vanishing in English-speaking countries, is a psychological thriller novella written by Dutch author Tim Krabbé, first published in 1984. The plot centers on a man whose obsession over the fate of his missing lover from years ago drives him to confront her abductor and pay the ultimate sacrifice in order to know the truth. The book was adapted into a 1988 film which was later remade in an English-language version by the same director.
