Rain lashed hard against the grimy diner window. Coffee steam swirled, obscuring the chilly autumn night. Detective Miles Corbin rubbed a tired hand across his face. He watched the scattered patrons, mostly weary truckers. A sudden siren wailed in the distant city streets. That sound rarely brought good news to his quiet town. Flo was wiping tables with a practiced, brisk motion. She paused, listening intently to the growing noise. Miles sighed, knowing his peaceful evening was now over. He pulled out his phone, dreading the impending call.
