The autumn wind howled through the empty dark streets tonight. Detective Mara stood alone on the cracked concrete sidewalk there. Rain fell softly onto her worn black leather coat today. A single yellow streetlight flickered above the dark crime scene. Yellow police tape fluttered in the cold October evening breeze. She stared at the body lying on the wet ground. The victim wore a crimson scarf around his pale neck. Blood pooled beneath his head like a dark crimson lake. No witnesses had come forward to speak with her yet. Mara pulled her notebook from her coat pocket very slowly.
