Thick fog choked the city. Rain lashed the dirty window. Detective Vance entered the room. Heavy silence greeted his arrival. A body lay perfectly still. Blood pooled on luxury carpet. The victim was brutally stabbed. Vance knelt by the corpse. Cold skin felt like marble. Her empty eyes stared upward. A shattered glass lay nearby. Lipstick stained the broken rim. Someone left in a hurry. Muddy footprints ruined the floor. They led toward the hallway. Sudden footsteps echoed right outside. Vance drew his service weapon. The killer was still close. Shadows danced along brick walls. He heard a floorboard creak. The heavy door swung open. A masked figure stood there. The real mystery just began.
