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.
