Originally designed to be a trilogy Simon took the step to extend the series by another book so that it wouldn't be rushed in any way. This I feel was not only a brave step by the author but a necessity as otherwise a lot of the beautiful prose along with descriptive work that has carefully been laid down in the previous two books would have been for nought and really not done justice to the pair of historical nemesis. Its well written, lovingly crafted by an author who cares for what he creates and above all deals with a period of history that France and Britain are both proud. It's going to be interesting to see the final build up to the epic conclusion of the series and one that's really going to enthral fans of historical fiction even though the outcomes set in stone. An author I sincerely wish I'd had teaching me history at school.
