The rain fell without mercy. Detective Harris adjusted his collar. A body lay in shadows. Blood pooled on wet cobblestones. A red scarf hugged her throat. Her eyes stared at nothing. A single gunshot broke silence. No witnesses came forward yet. Harris knelt beside the corpse. He examined the strange wound. It was no ordinary murder. A cryptic note was found. It read "Five words only." The detective frowned in confusion. This killer left a message. But why such strange precision? Harris pocketed the note carefully. He scanned the dark alley. Something glinted near the body. A tiny silver locket gleamed. Inside was a woman's photo. The victim's secret was revealed.
