I'm trying to find the name of a book that came out in paperback circa early '90's.

Was a horror book, with a redish cover and an emaciated face rising from it. Can't remember the author but was a reasonably famous one as I remember seeing an advertisement at the cinema.

Think the title is just one word. Don't know much of the plot, just that the first scene or two revolved around a graveyard and the main character watching someone acting odd over a grave.

Anyone know what I mean?
