Going back to the book, the author has managed to combine the suspense of the police, to the historic ambience of a Barcelona under the Franco era (and all that that implies in terms of social atmosphere). But the best is that it has created correctly as if the characters were known in an original scenario.
Carlos Ruiz Safon posted in this novel, "a book we love even more that can project themselves into it." For me this was the case, but also to all those to whom I advised.
In conclusion this is one if not the best book I have read for a long time.
PS: Congratulations to the translator who was able to transcribe the whole atmosphere, sensitivity and suspense of a bestselling Spanish.
