Ben Fogle wrote a book called "The Teatime Islands" which was a travelogue of the remnants of the British Empire. Places like the Falklands, Tristan da Cunha, St Helena, Ascension and Gibraltar.
Not as good as the similar book "The Last Pink Bits" by Raith Rovers fan Harry Ritchie.
Simon Winchester also wrote a similar book called "Outposts". Don't know what team he supports.
