Discover the stories of the brave men and women who worked, trained and fought across the UK in an unbelievable effort to defeat the Nazis and win the Second World War.

From the outset of the war, most of Britain felt like a mystery even to those who lived there. All road and railway signs were removed up and down the country to thwart potential enemy spies. An invisible web of cunning spread across the United Kingdom; secret laboratories were hidden in marshes, underground bases were built to conceal key strategic plans and grand country houses became secret and silent locations for eccentric boffins to do their confidential cryptography work.

In Secret Britain, Sinclair McKay maps out the UK through the hidden bases and battlegrounds of WWII. These locations are full of history and intrigue, but if you don’t know where to look, you might just miss them. Journeying through secret wildernesses, suburbs, underground tunnels and manor houses, Sinclair gives a glimpse into the stories of the incredible people behind the war effort, and shows how you might be able to visit these mysterious and evocative locations yourself.

With his trademark warmth and compassion, Sinclair unearths the truths of the war that have remained under layers of secrecy since the war was won in 1945.
