I heard an interesting thing about grammar and mystery novels when I was at Stanford the other day.
It's possible that clues appear more often in subordinate clauses than main clauses of mystery novels because people aren't as drawn to the subordinate clauses. The professor speculated that putting a clue in a subordinate clause is a way to hide it in plain sight.
Has anyone else heard this theory or noticed it in practice?
