[1] In 1993, journalist Donald McCormick claimed that Fleming based Vesper on Polish agent Krystyna Skarbek, who was working for Special Operations Executive when he knew her.

She poses as a radio seller, working with secret agent Rene Mathis, and later as Bond's companion to infiltrate the casino in Royale-Les-Eaux, where Le Chiffre frequently gambles.

After Le Chiffre's death, she tries to make a fresh start with Bond, but she realises this is impossible when she sees SMERSH operative Adolph Gettler tracking them.

Consumed with guilt and certain that SMERSH will find and kill both of them, she commits suicide, leaving a note admitting her treachery and pledging her love to Bond.

[The abrupt prosaic choice of vocabulary ending the novel may come from Christopher Marlowe's play The Jew of Malta where the following quotation serves as the definition of a lady: Later books in the series suggest that Bond still has feelings for Vesper, however.

[4] In this version, which bore little resemblance to the novel, Vesper is depicted as a former secret agent who has since become a multi-millionaire with a penchant for wearing ridiculously extravagant outfits at her office ("because if I wore it in the street people might stare").

Bond (David Niven), now in the position of M (John Huston) at MI6, uses a discount for her past due taxes to bribe her into becoming another 007 agent, and to recruit baccarat expert Evelyn Tremble (Peter Sellers) into stopping Le Chiffre (Orson Welles).

Though her ultimate fate is not revealed in the film, in the closing credits she is shown as an angel playing a harp, showing her to be one of the "seven James Bonds at Casino Royale" killed by an atomic explosion.

Vesper is initially skeptical about Bond's ego and at first is unwilling to pretend to be his girlfriend to distract the other players at the high-stakes Texas Hold 'Em poker tournament hosted by Le Chiffre.

Unknown to Bond, however, Vesper embezzles the tournament winnings and intends to deliver them to Adolph Gettler (Richard Sammel), who (like his novel counterpart) has been spying on them since they arrived in Venice.

When Bond receives a timely phone call from MI6 chief M (Judi Dench) and realises that Vesper embezzled the money, he pursues her as Gettler takes her hostage and throws her in a caged elevator.

[6] In the 2015 film Spectre, following Mr. White's suicide, Bond finds a VHS video tape in his hotel room in Morocco labelled "Vesper Lynd Interrogation".

Ernst Stavro Blofeld (Christoph Waltz), whose worldwide criminal organisation SPECTRE is the power behind Quantum, gloats that he is indirectly responsible for Vesper's death.
