All alone, 21-year-old Eliza (her mother is also dead) impulsively quits her safe teaching job at a nice girls' school to take up a position as governess at Gaudlin Hall in deepest Norfolk.
The advertisement requests the position be filled without delay and, less than a week after the death of her father, Eliza is on a train to Norfolk to take up her new role.
That's when things start to get scary. Arriving at the gloomy, crumbling mansion, it appears there are no adults in charge, no parents and no explanations, only the lugubrious, unsavoury Heckler who collects Eliza from the station as the previous governess makes a run for it.
No one's too keen to shed light on these mysteries.
From here on, it's best the story's not spoiled. Suffice to say things do more than go bump in the night as forces unseen pull off pretty gruesome stunts, which is why Gaudlin Hall has been going through governesses at an alarming rate.
Not one to be deterred by a handful of near-death experiences, Eliza seeks to unravel the mystery of the presence, but this cannot be done without confronting grave danger.

Although, if you're reading this alone, on a cold winter's night, with branches scratching against the windows and the panes rattling in their frames, you may want to sleep with the lights on.
