Had King Edmund Ironside's sons Edward & Edmund not been smuggled out of England to protect them from Danish King Canute, and had they not been caught up in the political affairs of Russia & Hungary, and had Edward not been murdered on his return to England when Edward The Confessor wished to appoint him heir instead of the imminent French Norman takeover of Anglo Saxon England, then we may have been living in a different country today. So many "Ifs" and questions, so many possible outcomes, this book reads like a modern-day thriller and throws up all the injustices and frightening uncertainties of Medieval England and beyond. Easy to read and well informed in its material and revelations, this book is a great find. Only occasionally does Ronay get stuck in rather technical cross-referencing as he tries to prove some more tenuous conclusions and theories (such as the actual identity of Edward's wife Agatha's mother & father) but overall this is a good bed-time read, and it will make you want to read other similar historical titles of the period - I did after finishing this 11th Century thriller!
