'Bastard Prince: Henry VIII's Lost Son' by Beverley Murphy

It took Henry VIII twenty eight years and three wives before he secured a legitimate male heir.  Yet he already had an illegitimate son with Elizabeth Blount, a member of the English gentry, her son’s name was Henry Fitzroy. 

The book begins with the life of Fitzroy’s mother, while this recognized mistress of Henry VIII had been a shadowy figure, the author fills in the gaps with the known information on her life and also discusses how King Henry may have considered making Fitzroy his heir, so how close did he come to being King Henry IX?
