Matilda Lockett is used to playing the role of Poor Dead Edna the Orphan on stage with her spirit-medium aunt, Signora Valentina, and theatrical uncle Barnabus - but when they all decamp to Beauchamp Manor to deal with a most dreadful haunting, she discovers she really can see ghosts! There she meets ghost boy, Edgar Wilde, who shares her love of supernatural snooping, and together they set about unravelling the case of The Ghosts of the Manor.
