His autobiographical novel "Borstal Boy" followed in 1958. In the vivid memoir of his time in St Andrews House, Hollesley Bay Colony Borstal, near Woodbridge, Suffolk, England. (The site of St Andrews House is now a Category D men's prison and Young Offenders Institution). An original voice in Irish literature boomed out from its pages. The language is both acerbic and delicate, the portrayal of inmates and "screws" cerebral. For a Republican, though, it is not a vitriolic attack on Britain; it delineates Behan's move away from violence. In one account, an inmate strives to entice Behan into chanting political slogans with him. Behan curses and damns him in his mind, hoping that he would cease his rantings-hardly the sign of a troublesome prisoner. By the end, the idealistic boy rebel emerges as a realistic young man, who recognises the truth: violence, especially political violence, is futile. The 1950s literary critic Kenneth Tynan said: "If the English hoard words like misers... Behan sends them out on a spree, ribald, flushed, and spoiling for a fight." He was now established as one of the leading Irish writers of his generation.
