I am trying to remember the name of a Wolfe short story (I think it was from Endangered Species, but I am not sure). It involves a woman and man on vacation at a beach house. The man sees a ship on the horizon one day, and shortly after that, the girl disappears and he goes searching for her. He strikes a deal with the captain of the odd ship in order to save her. I won't describe the ending so as to keep from spoiling it for someone else, but hopefully someone can help me remember the name! Thanks!
