Diarmaid MacCulloch's biography is much the most complete and persuasive life ever written of Thomas Cromwell, a masterclass in historical detective work, making connections not previously seen. It overturns many received interpretations, for example that Cromwell was a cynical, 'secular' politician without deep-felt religious commitment, or that he and Anne Boleyn were allies because of their common religious sympathies - in fact he destroyed her. It introduces the many different personalities of these foundational years, all conscious of the 'terrifyingly unpredictable' Henry VIII. MacCulloch allows readers to feel that they are immersed in all this, that it is going on around them.
