Query: BRILLIANT SCARY STUFF!!!

A young woman accepts the role of guardian and housekeeper to two young angelic children for a seemingly uncaring Uncle. Through her instant love for these two apparently innocents our heroine begins to have visions and contact with former members of the household. As it turns out these previous employees are both deceased and so it happens the hero of the book - together with Mrs Grose, her only ally in the building - set out to save the lives - and souls - of the children. No more will be said by me in these pages but be warned this novel is a classic horror story in more than one sense of the word.
