Sometimes it is also about Right v Wrong, but mostly it is about English cricket's failure to control - and, yes, often to understand - the most individualistic, egotistical, inspirational, crowd-pleasing cricketer of his generation...
Whether Pietersen realises it or not, it is also about a failed relationship.... In his drive for marginal gains, Flower once encouraged psychometric testing of England's players and one of the discoveries was that Pietersen was an introvert.... Flower is conventional, diligent, precise and rigid; Flower likes to plan and gives praise sparingly; Flower is a private man of great integrity who keeps his relationships on an even keel. Pietersen is the opposite. Pietersen is intensely emotional, lives for the moment, craves praise and dislikes criticism. By his own admission, he has no time for planning - he stares out of the window at team meetings and views coaches as largely redundant...
Pietersen's very presence repeatedly lays bare the problems of a conservative, fastidious and unwieldy hierarchy in handling the assertive individualism more prevalent in the modern game. The moment England start losing, and Pietersen's form dips, they get shot of him....
As for fake Twitter accounts and Tweetgate, why the coaching staff did not bang heads together and sort both in 24 hours is a question that lingers. In English cricket, authority is too often invested in those away from the action. England players' involvement in KP Genius displays a crass failure to recognise that with his ego came sensitivity...
He is a South African in England, a star player who needs his ego perpetually feeding, but who is not just excluded from the dressing-room clique but is mocked by it. When he asks for a break to see his wife and family, it is routinely refused. Others get their breaks: it is that IPL punishment thing again. Even his injuries - serious injuries - are disparaged by Flower. A fair and honest man, Flower's disenchantment with Pietersen begins to demean him....
....it is a legitimate work of propaganda (so much propaganda has been thrown in his direction, he had little choice but to reply in kind)....
But at a time when so many cricket autobiographies are cravenly dull, when player interviews are delivered as if by rote, and the governing body forever asserts its right to rule in near-secrecy, Pietersen's flawed and overwrought cri de coeur is a book that was better written...
