Novel that is similar to the horror movie “It Follows,” where there’s a relentless pursuer (and long intervals of dread and contemplation from the pursued)?

The intervals of dread occur between confrontations/close-calls with the pursuer. In other words, the story focuses on the uneasy moments between confrontations, where the terrorized characters must wonder when/how it will return.

Put more simply, I'm looking for something that matches the rich, eerie atmosphere of the film.

I'll also add that one of the film's most surreal and discomfiting concepts is that the pursuer can take on the appearance of a stranger or it can look like someone the characters know.

Is there a good novel out there that matches one or more of these aspects?
