When Charles I was executed, his son made it his role to seek out retribution, producing the biggest manhunt Britain had ever seen, one that would span Europe and America and would last for thirty years. When he ascended to the throne in 1660 as Charles II, his search for revenge intensified, with show trials in London and assassination squads scouring foreign countries. Many of the most senior figures in England were hanged, drawn and quartered; imprisoned for life; or consigned to a self-imposed exile, in constant fear of the assassin's bullet.History has painted the regicides and their supporters as fanatics, but among them were exceptional men, including John Milton, poetic genius and political propagandist; Oliver Cromwell's steely son-in-law, Henry Ireton; and the errant son of an earl, Algernon Sidney, whose writings helped inspire the founders of the American Revolution. Cromwell himself was subjected to the most bizarre symbolic revenge when—though long-dead—his body was disinterred and beheaded.Set in an age of intrigue and betrayal, The King's Revenge brings these remarkable figures vividly to life in an engrossing tale of ambition, double agents, and espionage.
