Last Half of Darkness: Society of the Serpent Moon

You receive a strange package with a scrawled note, a mysterious map and your fiancee's ring with blood on it! The return address on the package reveals it came from Antibes... where only a few days earlier she was sent to write and investigate a story on a series of vampire-like murders that have plagued the dark streets and alleys of the tiny European town. Your journey follows the path of clues left behind by your missing girlfriend, and along the way you will have to solve an ancient mystery and the source of evil causing the local townsfolk to turn into a rare breed of savage night-thirsty murderers.
