Markus Zusak said this quote

And I can promise you something, because it was a thing I saw many years later - a vision in the book thief herself - that as she knelt next to Hans Hubermann, she watched him stand and play the accordion. He stood and strapped it on in the alps of broken houses and played the accordion with kindness silver eyes and even a cigarette slouched on his lips. The bellows breathed and the tall man played for Liesel Meminger one last time as the sky was slowly taken away from her.
