Sixteen-year-old Nathalie Baudin's column for Le Petit Journal summarizes new arrivals at the morgue, a task she finds both fascinating and routine. When she has a vision of the newest body, a young woman, being murdered -- from the perspective of the murderer himself -- her search for answers eventually sends her into the Parisian Catacombs. Nathalie's psychic ability may make her the only one who can discover the killer's identity -- and she'll have to do it before she becomes a target herself.
