John Gillingham 
William II (Penguin Monarchs) [EPUB ebook] 
The Red King

William II (1087-1100), or William Rufus, will always be most famous for his death: killed by an arrow while out hunting, perhaps through accident or perhaps murder. But, as John Gillingham makes clear in this elegant book, as the son and successor to William the Conqueror it was William Rufus who had to establish permanent Norman rule. A ruthless, irascible man, he frequently argued acrimoniously with his older brother Robert over their father’s inheritance – but he also handed out effective justice, leaving as his legacy one of the most extraordinary of all medieval buildings, Westminster Hall.
