Once upon a time, I wrote a novel that was part character study and part mystery. It was split between the now and the back-in-the-day sections as Arthur Quinn tells his girlfriend a story about a scar across his shoulder. The stories were told in alternating chapters with one in the now and one back then. The goal was to show the changes in the character and the way he pokes around in other people’s lives.
A few agents read the novel and hated the structure. As one said, “Just as momentum built in one story, you were whipped back to the other.”
SO, I cut them apart and let them breathe as separate things. One mystery is Smokin’ Hot Mess and Off Season is the other.
