A merciless serial killer commits murders on a very disconcerting way: evilness and cruelty the same way wicked characters are depicted by folk tales that are part of the child horror cosmology.In this novel from scotch writter Craig Russell, people is slaughtered and tortured as Cindirella’s mother would, or Snow White’s, or the cannibal Little Red Riding Hood’s wolf, or Hansel and Gretel’s witch. These are sinister references to those histories, supposedly for kids, and scare us all at that age, “they are obscure, and it’s obscureness is ancient”.It all beguins when, on a beach, the corpse of a dead girl is found, and in her hand is a mysterious note: “I’ve been underground and it’s time to get back home”. Jan Fable, violent crimes department chief of Hamburg, has to follow this and other wicked clues left behind, unravealing symbols of the relentless human predator. He will be helped by an enigmatic witer who has published a book, Brother Grimm, where he propose that maybe childhood tales are true: monsters live among us, and they live in the forrest depths where our steps may lose and, worse, we may be devoured bu evilness itself.The novel masterly mixes the typical police stoy strokes with the folk tale references witch plots always discuss about good and evil, the search and the desolation, the fierce motivation of the executioner and victim’s innocence. Goodness and justice, as they are settled on modern civilization, suffers the slap on their ethic face from this killer, who declares he is the executor of the human spirit. “Europe’s spirit is Germany, and Germant’s spirit is Grimm”, says the killer. I recomend this book to all cop stories and horror tales lovers, and the ones who enjoy a well written and ploted.
