The rain fell steadily as Detective Harlan reviewed the shocking crime scene with focused urgency and care. Shadows danced along the walls while clues whispered secrets from every darkened corner of silence. Blood stained the wooden floor beneath the victim's motionless body in the crowded elegant room. Harlan knelt silently inspecting every detail hoping the evidence would finally reveal the hidden truth. Outside thunder rumbled across the stormy sky while witnesses waited anxiously for their important interviews.
