When a character is focused on a single objective, the flow of the story is fairly easy to maintain. Detective Sherry Sharp is after the psycho who killed her sister. She hears about another victim found downtown and she’s in the car on her way, enraged and determined.
How you get Detective Sherry from one place to another, and how you manage her emotions from one state to another will more or less take care of itself.
If, however, you have various objectives and storylines to contend with, things can get tricky.
