On a dark, stormy night, Detective Brown received an urgent call. A body had been discovered, brutally murdered, at an abandoned warehouse downtown. Without delay, he gathered his belongings and headed to the scene. The pouring rain cast an eerie shadow on the grim atmosphere as Brown approached the warehouse entrance. As he entered, Brown was greeted by the sight of a lifeless figure, the victim's eyes wide open, frozen in terror. A chilling silence filled the air, broken only by the sound of distant thunder. The detective carefully examined the crime scene, noticing a single clue: a mysterious letter addressed to him, left on the victim's chest.
