Yeah, I keep finding those crumbs. Last year I was reading “The Night Circus” and a single phrase, “the moon is a broken mirror,” kept floating around in a couple of scenes. I thought it was just poetic, until the very last chapter I saw the moon reflected in a silver tray at a circus tent, and the mirror was actually a broken carnival mirror that the magician used to trap memories. It felt like the whole book was just teasing you with a single line that only made sense when the final reveal hit. The twist? The broken mirror was actually a portal that the protagonist used to pull the audience into the circus. It was a neat, almost invisible thread that finally tied everything together.
