Rain lashed the windows, a rhythmic, drumming sound. Detective Harding stared at the body on the floor. A single red rose lay beside the still hand. The air hung heavy with the metallic scent of blood. Someone had ended a promising young life too soon. He noticed a small, ornate silver locket nearby. This scene whispered secrets only keen eyes could hear. The investigation had just officially, sadly begun now.
