So after chapters focused on London, its time to cast our gaze outwards for an episode… as Edward III, the young, dynamic and energetic King of England, finds himself dragged into a war with Scotland, which in turn leads to a war with France… and how this, mixed with complicated French dynastic politics, to produce the conditions that led to the start of the 100 Years War.

Covering how the country slid into this war, the seemingly constant set backs and occasional brilliant victory at sea, and Edward virtually bankrupting the nation, ‘Thunderbolt’ sets up the situation in London, with the king turning up in the Tower and trying to purge his entire government for backsliding. Wild times abound.
