Farrell's next book, "The Siege of Krishnapur", and his last completed work, "The Singapore Grip", both continue his story of the collapse of British colonial power. The former deals with the Indian Rebellion of 1857. Inspired by historical events such as the sieges of Cawnpore and Lucknow, the novel is set in the fictional town of Krishnapur, where a besieged British garrison succeeds in holding out for four months against an army of native sepoys in the face of enormous suffering before being relieved.
