The grand ballroom sparkled with chandeliers and wealthy society guests. Detective Sarah Mills adjusted her evening gown while scanning faces. She hadn't expected to work tonight at this charity event. The mayor's wife approached with champagne and a bright smile. "Detective Mills, how wonderful you could join us this evening!" Thunder crashed outside as rain began pelting the mansion windows. Sarah noticed the lights flickering ominously throughout the ornate dining hall. A piercing scream suddenly echoed from the library down the hallway. All conversation stopped as guests turned toward the terrifying sound. Sarah immediately rushed through the crowd toward the source area. She found the host lying motionless beside his mahogany desk. Blood pooled beneath his head on the expensive Persian carpet. The library window stood wide open to the stormy night. Sarah quickly checked for a pulse but found absolutely nothing. She turned to face the gathering crowd of shocked guests. Another murder case had just landed directly in her capable hands.
