Neil Oliver follows the rise of Clan Stewart to become Scotland’s Royal dynasty. It’s the blood soaked tale of a bitter family feud. In a vicious contest, using clan power to plot, manoeuvre and murder their way to power, the story culminates with the dramatic assassination of King James I below a tennis court in Perth, 1437. Neil traces this family feud through clan combat, royal romances and spectacular Renaissance courts to the brutal torture and execution of the last rival Stewart, Walter Atholl, when the king’s widowed Queen Joan wreaks a terrible revenge for his treachery.
