Writer James Gavin has produced Deep in a Dream: The Long Night of Chet Baker. It's a biography of the jazz trumpeter and vocalist. Baker came from Oklahoma in the 1950s to become the "prince of cool jazz" on the West Coast. His death in Amsterdam in 1988 seems to have been drug-related. Gavin provides some answers to the riddle of his death. Gavin is a frequent contributor to The New York Times and other publications.
