When they went on holiday to Venice, Bond found out that Vesper had stolen the proceeds of the Le Chiffre gamble.
But Bond survived, although seriously wounded, and during his recovery Vesper fell in love with him. Le Chiffre set a trap for Bond, and had him tortured. Le Chiffre indeed sponsored various terrorist organizations, luring them into attacks on companies that Le Chiffre wanted to take over.
In this movie, she was an accountant for MI6, supporting James Bond (role by Daniel Craig) to defeat the villain Le Chiffre at the gambling table. Vesper Lynd was portrayed by Eva Green in the Eon production 'Casino Royale' (2006).
