John reminded me I meant to talk about how to hide a clue in a sentence. The trick is to do the sentence WRONG, because the clue is the most important thing, and usually you want to put that in the main clause or at the end. But to hide it (while still being fair and putting the clue in there), you should think about burying it, like in the middle of a series of three or four, or in a subordinate element, like a dependent clause or a modifier. Like:
Kaylie pawed through the trunk, tossing out a string of fake pearls, an old Bible, and a Colt-45. She couldn't find that hat anywhere.
The old Bible is the clue, but it's in the most dismissive place, and followed also by something dramatic (a pistol). It's all about distraction, I guess!
Those of you who have written mystery or suspense, how have you buried clues?
