The Wife of Willesden, novelist Zadie Smith’s captivating playwriting debut, is a contemporary version of The Wife of Bath’s prologue and tale from Chaucer’s Canterbury Tales. As many an English major will attest, Alyson, the Wife of Bath, is the most colorful of the pilgrims whose verse monologues form the bulk of Chaucer’s 14th-century masterpiece. Using rhymed couplets with 10 syllables per line (as did Chaucer), Smith has transformed Alyson to Alvita, a Jamaica-born Londoner of today, in a comedy faithful to its source material yet discerning about contemporary social issues.
