As a writer, I'll use violence when necessary in my mysteries. My westerns pull no punches. The American West was a violent time. When writing about murder and mayhem, I'm not too squeamish, which probably relates back to my days practicing criminal law. People do bad things. The redemption story - and appropriate punishment - are at the heart of most memorable mysteries.
But when my daughter's first day of classes at her university were cancelled because an escaped killer (two law enforcement officers slain) was on campus, I experienced one of those horrible mother moments when your stomach literally knots and you can't breathe. If I hadn't been with my writing friends, having our monthly plotting session, I'd have been flying down the road, pedal to the metal, to her school to protect my baby. Fortunately, cooler heads prevailed, and we continued to work on plot problems, all the while praying for calm and the police. The bad guy was apprehended, the campus went back to normal, and I can breathe again.
Real life is much scarier than fiction, trust me. It takes a lot of prayer to see through the darkness.
