The storm raged fiercely as Detective Grey arrived at midnight. A lifeless body lay sprawled beneath the dimly lit chandelier. Shattered glass glistened like diamonds around the victim's cold hand. A single crimson rose rested gently on the bloodstained floor. Whispers echoed softly from corners cloaked in creeping shadows. Grey noted every detail with meticulous and unwavering precision. Outside, thunder rolled deeply while the clock struck the thirteenth. In this mansion, secrets hid behind every locked, creaking door. Each suspect’s alibi unraveled under Grey’s sharp, piercing gaze. Tonight, justice would emerge from darkness, cold and unforgiving.
