Halloween Themed Story/Modern AU: A disappearance and a murder lead part-time paranormal investigator Hiccup Haddock and his team to a grim discovery. Uncovering a decades old secret, can they solve the mystery and escape with their lives? Rated M for adult themes. A/N: The annual Halloween story-this time based on a plot suggestion by Valka 411. A bit of a departure this one as it's a cross between a ghost story and a detective story. M rating is for references to adult themes and murder. Enjoy.
