By António Lobo Antunes
320 pages; W.W. Norton & Co.
The Fat Man and Infinity, a collagelike memoir composed of newspaper and magazine columns, or crónicas, should win the celebrated Portuguese novelist António Lobo Antunes a devoted U.S. readership. "I'm not an elderly man with the heart of a child," he cautions, guiding the reader through evocative scenes from his past, in a suburb outside Lisbon, and his enigmatic present. "I'm a child whose envelope has grown slightly worn." Translator Margaret Jull Costa expertly transports these wine-dark meditations across the sea.
