This is a short, but very interesting book on a crucial year in the life of Henry VIII. In this one year, Henry's first wife died, he suffered an accident while jousting which ended his career as an athelete, he killed Anne Boleyn, lost his illegitimate son, the Duke of Richmond, married a third time, and faced a rebellion in the north over his monastic policy. All of this cope with in one year and Henry also faced the psychological issues of getting older and, yes, fatter. At 6'2" he was to become morbidly obese, ending up with a 56 inch waist. All these traumas had, as Suzanne Lipscomb argues, a significant impact on Henry's psychology and his later reign.
Lipscomb argues convincingly that Henry probably believed that Anne had cuckolded him and this was the reason for the rapidity of her judgement and execution. This act of marital infidelity and the rebellion in the North, the Pilgrimage of Grace made Henry disinclined to trust anyone at all and as such made him more likely to trim heads and ask questions later. I think this is an excellent piece of analysis and like Lacy Baldwin Smith's short book on the latter portion of Henry's reign, likely to be influential among Tudor historians.
