The Cherry Knife Killer has returned to the ocean city of Trevia. Eight detectives took on the case; eight detectives disappeared. In this peaceful city, the administration wants to keep everything under control. It's up to Yen Monroe to solve the greatest of mysteries. Young and inexperienced, he's undoubtedly a risky bet on the mayor's part. Perhaps he's the key to catching the killer, or perhaps not; perhaps he will just be another headstone in the cemetery. An unconventional duel. Inexperience versus the supernatural and the paranormal. One may win, or both may lose. It is up to Yen. Of course, little "distractions" will appear along the way, as usual. He's not the only detective in the area who wants to make history.
