The last novel of Mantel’s Cromwell trilogy is approached through the lens of the contemporary theory of power. As a historical novelist, Mantel opens up the mentality behind political and social forms of power under Tudor monarchy, the dominance of traditional medieval system and, in Cromwell’s attempt to create bureaucratic government, the emergence of power devoid of the coating of sacredness. The paper is focused, though, on what is seen as the novel’s central plot, the dynamics of interpersonal balance of power between king Henry VIII and his Lord Privy Seal. Seemingly, Cromwell enjoys his outstanding career, unique for a commoner, as long as Henry stands behind him, and once Henry has exhausted Cromwell, he gets rid of him. The main phases of dynamics between Henry and the central character are established, and each phase of the increase in Cromwell’s power and outward prestige is accompanied by the increase in his awareness of the dangers of his position, in case he fails to satisfy his master’s desires. In fact, Henry realizes that Cromwell presents a challenge to king’s power, comes to see him as a dangerous rival and executes Cromwell as such. Cromwell’s fate is destined to repeat that of his fi rst master Cardinal Wolsey. Mantel’s artistry in implying and explicating this plot on the novel’s many levels is analyzed.
