Agnes Quill is the story of a teenage detective, the haunted city she lives in, the strange cases she solves and the ghosts who help, hinder or just plain annoy her. Set in Legerdemain - a congested, fog-filled, cobblestone-paved Victorian city built around a cemetery the size of Central Park - Agnes' adventures include confrontations with trapped spirits, cursed souls, possessed relatives, disappearing pets, decapitated scientists, ambitious zombies and a mess of other supernatural oddities.
