As the Wikipedia article notes, even the title of a chapter or an entire work can give us such a hint. I once changed the title of a novelβ House of Stars , currently seeking a publisherβbecause the original working title gave away too much of the plot.
So in ch. Romantic suspense novels are given to this trope, since a primary purpose of the foreshadowing is to build anticipation and suspense. For example, Elizabeth Peters was a master of the witty, light-hearted romantic suspense story. In Summer of the Dragon , we see a whole series of such hints. It was like a game. I know now what it was that woke me at the crack of dawn next morning; but at the time I was amazed at myself. The fact is, my compassion was stupid. If I believed in premonitions I would claim that I knew the next day was going to see some sort of climax.
In fact, that may have been just what the author was going for. Her laugh-out-loud description of the cover of a Gothic romance at the beginning of The Camelot Caper shows that she knew exactly what she was poking fun at.
Some authors are particularly fond of this technique. As the examples indicate, this particular type of open foreshadowing by the narrator tends to occur especially in first-person narratives. When the Fellowship of the Ring reaches Lothlorien, Frodo sees Aragorn lost in memory of meetings with Arwen there in days long past.
I think everyone is familiar with that spoiler. But sometimes the later-placed-earlier scene seems to be designed to set up our expectations, more or less explicitly. But minor spoiler here that scene, which is presented in several places during the story, is always incomplete and carefully limited; and when it finally occurs, the context makes it quite different from what we were led to expect.
