It's a dead woman lying in the road! Susan panics. Did she hit this pedestrian? After calling for help, she notices that the body lying dead on the road is her school's assistant principal, Melissa Chadwick. Her detective daughter arrives at the scene and sensing something isn't right, discourages her mother from admitting guilt. Is this an accident, or a murder?

Feeling responsible, retired teacher Susan Wiles puts on her sleuthing cap, determined to find the answer. Will she find out the truth, or will tragedy once again strike the cozy New York town of Westbrook?
