Some of our most intriguing history is missing. Perhaps there has been a conspiracy, a cover-up? Or maybe some stories have been lost, forgotten or were just too embarrassing to talk about at the time? But now they are back, revealed in all their glory: secret passages, events, societies, loves, identities and even dark secrets of the grave.

After much sleuthing, Justin Pollard takes us into undisclosed historical waters to discover why the city of Burlington isn't on the map; how 'Agent Pickle' saved the lost treasure of Bonnie Prince Charlie; what Sir Thomas Overbury knew in 1613 that got him murdered with a poisoned enema and how Virginia Woolf sweet-talked her way aboard HMS Dreadnought dressed as Abyssinian Prince.

Secret Britain also reveals the tragic love story behind the Rolls Royce mascot; how agent Garbo managed to get an MBE and an Iron Cross; the sinister properties of the Hand of Glory; the lost smuggling ship Peggy; the Mystery Runner of Nos Galan; the extraordinary history of the Fairy Flag of Dunvegan; London's only Nazi war memorial and the secrets of the WWII Monopoly board.
