El enigma de Anne Wallace

Anne Wallace is the world's greatest pianist, but she's also an eccentric and unpredictable woman. Famous for her sublime intelligence and her love of the ancient, she plays a piano specially made for her, with all black keys. She often does so in the rain, on those stormy afternoons that lash the cliffs of the Basque coast near her home. Just after receiving the Prince of Asturias Award, Anne attends a cocktail party at a luxurious hotel with the other laureates. It is there that a bomb explosion—something inexplicable in a closed venue with stringent security measures—triggers a complex investigation in which she, as special as she is mysterious, becomes the prime suspect… and the only one capable of helping the astute Inspector Bieda uncover the truth.
