We often withhold information to create suspense. But at what point do you start withholding?
I think if you start the withholding too soon you could just confuse the reader. How do you decide where to start withholding?
For example, let's say there's a phone call to the character. She picks up the phone and says, "Hello?"
So the info in the phone call is the secret that you don't want revealed yet. Would you stop right there, maybe end the scene there? Or would you have her listen (just "she listened and then hung up"-- no info) and then end. Or?
I'm wondering if the caller should be revealed and only the content withheld?
How do you decide where "suspense" begins?
