Here is the opening scene of a murder mystery: Detective Jameson sat alone in his office sipping lukewarm coffee. Abigail knocked softly on the door and entered quietly behind. Morning sunlight filtered through dusty blinds illuminating worn wooden furniture. A FedEx delivery woman stood at his desk holding package. Gray clouds gathered outside obscuring the bright blue morning sky. A chill ran down his spine at the unexpected visitor. She extended her hand with an apologetic nervous smile present. The cardboard box was sealed with brown packing tape securely. He signed for the delivery with a flourish of signature. His curiosity was piqued as he cut the tape carefully.
