Katie and Maverick are out for their walk when Maverick dashes through the moving gate at a self-storage facility and they get locked in. By the time the police respond to the silent alarms the pair have set off, the smell of exhaust fumes has begun to seep from one of the garage-sized units, and the car inside is quickly engulfed in a ball of flame. Was it a suicide that turned extra messy, or did someone rig the expensive sports car to explode and kill the woman inside? When Katie starts to ask the tough questions, it seems there were a long list of people who didn’t much care for Sophie Grainger and several of them had motives for murder. But Katie also has her days full with the upcoming holiday season and her students who are participating in a mock-trial competition. Will the kids make it to the state finals under the expert coaching of a local attorney who has joined their team? And will Katie and Maverick have a wonderful Christmas this year, the first in which Katie’s dad has been home since the horrific shooting incident that nearly killed him?
