Washington - Because of the investigation led by three University of South Florida researchers, and because of exemplary journalism by the Tampa Bay Times, we now have an intensely discomforting but welcome enrichment of American literature. It requires artistry to write beautifully about children suffering at the hands of evil men, and from the riveting first sentence of his slender new novel “The Nickel Boys” -- “Even in death the boys were trouble” -- Colson Whitehead’s prose unfurls with controlled fury as he reimagines life at what was the Arthur G. Dozier School for Boys in Marianna, Florida.
