What the Twilight Says collects Derek Walcott's essays from over twenty years. It includes Walcott's moving and insightful examinations of the paradoxes of Caribbean culture (including his noted Nobel Lecture), and his reckonings of the work and significance of such poets as Robert Lowell, Joseph Brodsky. Robert Frost, and Ted Hughes and of the novelists V.S. Naipaul and Patrick Chamoiseau.

The book also contains Walcott's short story "Cafe Martinique," which traces the life of a colonial writer who is trapped in the values of the nineteenth century. What the Twilight Says reveals that Walcott is a writer whose prose has the same lyric power and syncretic intelligence that have made him one of the major poetic voices of our time.
