Angleterre, 1527. Dynastie des Tudors. Thomas Cromwell est le secrétaire du cardinal Wolsey, le conseiller favori d'Henri VIII. Mais les rois sont inconstants.

Ce dernier veut se débarrasser de Catherine, et le cardinal Wosley échoue à obtenir du pape Léon X l'annulation du mariage royal. Thomas pourrait tomber en disgrâce avec son maître, mais c'est compter sans son habileté et son art politique...

England, the 1520s. Henry VIII is on the throne, but has no heir. Cardinal Wolsey is his chief advisor, charged with securing the divorce the pope refuses to grant. Into this atmosphere of distrust and need comes Thomas Cromwell, first as Wolsey's clerk, and later his successor. Cromwell is a wholly original man: the son of a brutal blacksmith, a political genius, a briber, a charmer, a bully, a man with a delicate and deadly expertise in manipulating people and events. Ruthless in pursuit of his own interests, he is as ambitious in his wider politics as he is for himself. His reforming agenda is carried out in the grip of a self-interested parliament and a king who fluctuates between romantic passions and murderous rages.
