Background: John Anthony Burgess Wilson,  (25 February 1917 - 22 November 1993) - who published under the pen name Anthony Burgess - was an English writer and composer. From relatively modest beginnings in a Catholic family in Manchester, he eventually became one of the best known English literary figures of the latter half of the twentieth century. Although Burgess was predominantly a comic writer, his dystopian satire A Clockwork Orange remains his best known novel. In 1971 it was adapted into a highly controversial film by Stanley Kubrick, which Burgess said was chiefly responsible for the popularity of the book.
Context: After a brief period of leave in Britain during 1958, Burgess took up a further Eastern post, this time at the Sultan Omar Ali Saifuddin College in Bandar Seri Begawan, Brunei. Brunei had been a British protectorate since 1888, and was not to achieve independence until 1984. In the sultanate, Burgess sketched the novel that, when it was published in 1961, was to be entitled Devil of a State and, although it dealt with Brunei, for libel reasons the action had to be transposed to an imaginary East African territory similar to Zanzibar, named Dunia. In his autobiography Little Wilson and Big God (1987) Burgess wrote:  "This novel was, is, about Brunei, which was renamed Naraka, Malay-Sanskrit for 'hell.' Little invention was needed to contrive a large cast of unbelievable characters and a number of interwoven plots. Though completed in 1958, the work was not published until 1961, for what it was worth it was made a choice of the book society. Heinemann, my publisher, was doubtful about publishing it: it might be libellous. I had to change the setting from Brunei to an East African one. Heinemann was right to be timorous. In early 1958, The Enemy in the Blanket appeared and at once provoked a libel suit."  About this time Burgess collapsed in a Brunei classroom while teaching history and was diagnosed as having an inoperable brain tumour. Burgess was given just a year to live, prompting him to write several novels to get money to provide for his widow. He gave a different account, however, to Jeremy Isaacs in a Face to Face interview on the BBC The Late Show (21 March 1989). He said "Looking back now I see that I was driven out of the Colonial Service. I think possibly for political reasons that were disguised as clinical reasons." He alluded to this in an interview with Don Swaim, explaining that his wife Lynne had said something "obscene" to the British Queen's consort, the Duke of Edinburgh, during an official visit, and the colonial authorities turned against him. He had already earned their displeasure, he told Swaim, by writing articles in the newspaper in support of the revolutionary opposition party the Parti Rakyat Brunei, and for his friendship with its leader Dr. Azahari. Burgess' biographers attribute the incident to the author's notorious mythomania. Geoffrey Grigson writes,  He was, however, suffering from the effects of prolonged heavy drinking (and associated poor nutrition), of the often oppressive south-east Asian climate, of chronic constipation, and of overwork and professional disappointment. As he put it, the scions of the sultans and of the elite in Brunei "did not wish to be taught", because the free-flowing abundance of oil guaranteed their income and privileged status. He may also have wished for a pretext to abandon teaching and get going full-time as a writer, having made a late start.
Question: did he have any failures?. Whats the answer?
