'There is nothing new under the sun', a phrase ascribed originally to King Solomon, applies to the present book, with echoes of 'modern' themes exposing royal scandal, sex, corruption, political absolutism - attempted - religious controversy, danger of mass-terrorism, murder and 'suspicious' deaths, 'fake news' and international threat from superpowers. And all focusing on inside stories which today would be 'investigative journalism' with huge popular media interest. This is history for both specialists and, especially, for general readers, given media interest, including TV and film coverage in 'exciting' popular history, as set out by the author.

The earlier 'Royal Mysteries' in the series were full of tragedy, suffering, pathos, heroism and romance, but the present set are equally interesting and disturbing and revisionist. These include the alleged attempt to murder James I and VI before the became King of England; the scandal at court involving 'poisoned tarts', James' 'toy-boy', and a subsequent murder trial. And the following questions and mysteries: did Charles II really promise to convert to Catholicism to please Louis XIV; did Charles marry his mistress Lucy Walter, mother of rebel Duke of Monmouth; was James II and VII an enlightened religious reformer or trying to convert England to Catholicism - the religion of European superpowers; did George I 'disappear' (a 'hit' in modern terms) his divorced wife's lover before ascending the English throne; did the unpopular Duke of Cumberland murder his gay lover; did the hugely admired 'respectable' George III, devoted husband and father, marry a middle-class Quaker woman?
