The rain drummed softly against the cold, empty courtroom walls tonight. Detective Harris arrived quietly, eyes scanning the silent, dimly lit room. A bloodstained letter rested on the polished, cracked wooden bench. Footsteps echoed faintly as a shadow moved behind the velvet curtain. Suddenly, a scream shattered the silence, echoing through hollow halls. Harris ended his breathless pause, stepping cautiously toward the scene. A single candle flickered, casting ghostly shadows over the lifeless figure. In her hand, clenched tightly, a silver dagger gleamed sharply. Whispers of secrets and lies filled the dark, suspect-laden air tonight. The mystery had only just begun, secrets buried beneath polished veneer.
