Secret War in Portugal [1939-1945]
For SOE [British Special Operation Executive] 24 Land was the code name for Portugal

The Line...

Published in 1943 this book was issued in a facsimiled edition in 1999. It's a description of the Coast of the Sun, the mythical place were many of the spy stories occurred. «To love you have to know» it's the motto of this work that brings us back not only the landscape but also the people that since the end of the XIX century made first Cascais then Estoril as a first class place for leisure and secret encounters, in short, the ideal nest for the world of the shadows.
If some of these that are writing abroad about the secret war in this country could read Portuguese I would recommend this masterpiece from Gonta Colaço e Maria Archer.Unfortunately that it is not the case.
