Bech at Bay

240 pp. In this, the final volume in John Updike's mock-heroic trilogy about the Jewish American writer Henry Bech, our hero is older but scarcely wiser. Now in his seventies, he remains competitive, lecherous, and self-absorbed, lost in a brave new literary world where his books are hyped by Swiss-owned conglomerates, showcased in chain stores attached to espresso bars, and returned to warehouses three weeks after publication.
