Isabella and the strange death of Edward II

In chess, from the time of Queen Isabella of England, the queen has been considered the most powerful and feared piece on the board. Known to chroniclers as the 'she-wolf', Isabella, daughter of Philip IV of France, married King Edward II of England in 1308 in a union intended to create a lasting peace between the two countries. But after 13 years of enduring her husband's unkind and dissolute nature she fled abroad. With her lover, the exiled Roger Mortimer, she raised an army of mercenaries and invaded England, successfully deposing Edward.

Popular belief holds that Edward was murdered in an infamous manner at Berkeley Castle near Gloucester, at the order of his wife and her lover. But after Mortimer's execution a letter arrived at court that cast doubt over Edward's death and raised the possibility of his escape. The evidence remains controversial to this day, and here Paul Doherty examines it in his fascinating detective study, set in one of the most turbulent and exciting periods of English history.
