Fleur Jaeggy is often noted for her terse and telegraphic style, which somehow brews up a profound paradox that seems bent on haunting the reader: despite a sort of zero-at-the-bone baseline, her fiction is weirdly also incredibly moving. How does she do it? No one knows. But here, in her newest collection,I Am the Brother of XX, she does it again. Like a magician or a master criminal, who can say how she gets away with it, but whether the stories involve famous writers (Calvino, Ingeborg Bachmann, Joseph Brodsky) or baronesses or 13th-century visionaries or tormented siblings bred up in elite Swiss boarding schools, they somehow steal your heart. And they don’t rest at that, but endlessly disturb your mind.
