Detective Vance stared down at the lifeless body lying cold upon the damp floor of the dimly lit basement. Shadows danced across the stone walls while distant thunder echoed loudly through the heavy, oppressive silence of the stormy night. A silver pocket watch ticked slowly beside the motionless fingers, marking time that the unfortunate victim no longer possessed. Stepping carefully over shattered glass, the weary investigator knelt beside the corpse to search for any hidden clues regarding the murder.
