The heavy rain pounded against the dark and slick pavement. A single streetlamp flickered above the body on the ground. Crimson blood pooled slowly beneath her pale and motionless hand. Detective Miller stepped under the yellow tape with a sigh. He knew this murder would haunt him for many years. A silver knife glistened near the edge of the drain. The killer left no prints on the smooth metal handle. Someone watched from the shadows just beyond the police line.
