Throughout her career Wharton wrote ghost stories, and is a central figure within the genre in the twentieth century. When she collected many of her ghost stories together in Ghosts (1937) she put them under the 'special protection' of Walter de la Mare. Like him, she manages to evoke uncannily convincing atmospheres and characters, and in such stories as 'Afterward' the way in which the tale is told is so satisfying that one can only admire her craftsmanship. Wharton's collection Ghosts is described by E.F. Bleiler as a 'landmark volume in supernatural fiction', and to this we have been able to add a number of other tales of the supernatural, many of which will be unknown to her readers.
