This was the first book where I had to get into the politics of the day from the perspective of London. It was hard to move my characters from their homes in Devon, but it was important to show how the King and his adviser, Hugh Despenser, were ruling the nation. Despenser was, in effect, running the country in the King's name, and abusing it as though he was in charge of a massive protection racket. It was thoroughly enjoyable to write. I was able to take the example of a poor woman in the service of the Queen and look at how her murder could affect people, bearing in mind the killer was almost certain to be one of the most powerful people in the land. Baldwin and Simon had to walk a tightrope between conflicting interests amongst nobles, the King and his advisers, and a ferociously alarming woman who sought to recover her lost fortunes: the Queen.
