DAVID FELDSHUH'S powerful Miss Evers' Boys (below) looks at the warped logic that allowed a group of black share-croppers in Alabama in the Thirties to become guinea-pigs in a US government "health" programme monitoring the effects of untreated syphilis. Moving between the 1972 deposition of Miss Evers, the black nurse whose good intentions paved the road to hell, and a chronological account of pointless suffering, this is not for the faint-hearted.
