Accordion Crimes traces the long odyssey of a button accordion, an instrument made by a Sicilian who immigrates to New Orleans in 1891. Imprisoned in a round-up of Italian suspects after the political murder of the chief of police, the accordion maker is lynched, and his accordion falls into the hands of Apollo, a black steamboat screwman. The instrument begins its long, erratic voyage through 20th-century America, passing through the hands of the descendants of slaves, immigrants and their children, some of whom learn that the cost of becoming American is to surrender the private definition of self.

Accordion Crimes is alive with vividly drawn characters who sometimes meet violent, strange ends, and who, at other times, succeed in a hard world. Filled with indelible images, Proulx's latest novel is charged with sardonic wit and is, at different turns, darkly hilarious and heartbreakingly sad. What we see as the accordion weakens and disintegrates is a haunting and ominous sense of what is America.
