Since Mary's return to Scotland, the big question had been, who would she marry? The man she married would control Scotland and achieve great wealth and power. For the ambitious Scottish noblemen, Mary was a prize worth fighting for.

It didn't take long for Mary to realise that Darnley was a drunken idiot and she wished she'd never married him.
