How do you keep the audience guessing in your mysteries?
I love this question because the answer is a mystery. My books have a main plot and one or more subplots. These plots always get resolved with no loose ends. Should I be stumped by what should happen next as I'm writing the book, I go to bed wondering what to do. The answer comes by morning and I head for the computer. I'm often amazed at how things fit together. It's just the creative process at work.
