The relentless rain soaked the cobblestones outside the old theater where the night's final performance had just ended in silence. Inside the dimly lit auditorium, the stage manager discovered the lead actor's dead body slumped over a sharp prop sword. A single spotlight still shone upon the empty stage, casting eerie shadows across the scattered sheets of faded old music. The detective knelt beside the body, noticing a single very delicate red rose now resting on the actor's cold chest. A faint whisper of perfume hung in the air, mingling with the metallic scent of freshly spilled warm red blood. Through the old grimy window, sudden lightning flashed brightly, illuminating the murderer's shadow retreating silently into the narrow dark alley.
