Paulo Coelho 
Spy 

When Mata Hari arrived in Paris she was penniless.Soon she was feted as the most elegant woman in the city.A dancer who shocked and delighted audiences; a confidant and courtesan who bewitched the era’s richest and most powerful men.But as paranoia consumed a country at war, Mata Hari’s lifestyle brought her under suspicion. Until, in 1917 she was arrested in her hotel room on the Champs Elysees and accused of espionage.Written as a series of letters, The Spy tells the unforgettable story of a woman who dared to break the conventions of her time, and paid the price.
