Types of Clues
When watching or reading mysteries, I find myself distinguishing between two major types of clues.
The first is where the clue is supplied by the narrator or filmmaker either explicitly or subtly. This can happen, for example, when a paragraph describing a crime is followed by a paragraph describing a character, suggesting guilt by association. In film it can happen when the music subtly changes or when the camera lingers on a character’s facial expression indicating thought, worry, guilt, etc.
The other is the type of clue that are observable by the characters themselves, such as objects left in a room, windows left open, warm tea pots, etc. As readers and viewers, we see the details without bias, as the characters see them.
Both of these types can be (and often are) misdirections, but they feel very different whether they are productive clues or red herrings.
My question is what are these two types of clues called? Have I omitted another major type of clue? Do others feel like the narrative/filmmaker clues are less satisfying than the ones the other characters see? Thoughts?
