Borstal Boy is a 1958 autobiographical book by Brendan Behan. The story depicts a young, fervently idealistic Behan, who loses his naïveté over the three years of his sentence to a juvenile borstal, softening his radical Irish republican stance and warming to his British fellow prisoners. From a technical standpoint, the novel is chiefly notable for the art with which it captures the lively dialogue of the Borstal inmates, with all the variety of the British Isles' many subtly distinctive accents intact on the page. Ultimately, Behan demonstrated by his skillful dialogue that working class Irish Catholics and English Protestants actually had more in common with one another through class than they had supposed, and that alleged barriers of religion and ethnicity were merely superficial and imposed by a fearful middle class. The book was banned in Ireland for unspecified reasons in 1958; the ban expired in 1970.
