*Vesper Lynd (9 March 1983 – 4 August 2006) was a British HM Treasury liaison officer and a secret double agent blackmailed into working for Quantum. She worked with MI6 agent James Bond on his mission to bankrupt and capture Le Chiffre in Montenegro, during which time she began a close romantic relationship with him.

Eventually, she betrayed Bond to Quantum and subsequently died in front of him, which would emotionally scar and define him for the remainder of his life, even during his relationship with Madeleine Swann.

Vesper Lynd is a foreign liaison agent from the HM Treasury's Financial Action Task Force assigned to make sure that Bond adequately manages the funds provided by MI6 for the high-stakes poker game at the Casino Royale. However, she is secretly a double agent working for Quantum, the terrorist organisation MI6 is trying to stop. She is an unwilling traitor however; she is only helping Quantum because they have taken her lover Yusef Kabira hostage and threatened to kill him if she does not cooperate.

Vesper Lynd was an intelligent and perceptive person who was able to guess information about a man simply based on his behavior and mannerisms as demonstrated during her first meeting with Bond. She was also very attractive and elegant, so like many women, she likely feared not being taken seriously by her male colleagues and overcompensates by dressing in a slightly masculine manner, although she also enjoyed wearing evening gowns and makeup. Because of her intellect, Vesper could be suspicious, rebellious and even icy in certain situations, sometimes making false inferences about those around her and therefore; making poor judgments about them, as was the case on several occasions in her relationship with Bond.

Vesper was nevertheless sociable and rather sensitive, hence her ability to bond easily with men, even after tense exchanges. She was also very averse to violence to the point of being traumatized after witnessing a murder in which she herself participated (such as that of Steven Obanno) but she was ready to do anything for Yusef Kabira, including betraying his cause if he were to be in danger, unaware that the man was actually using this asset to manipulate her in secret. Vesper, however, felt horrible feelings of guilt at siding with her enemies to the point of becoming suicidal, which eventually led to her demise.*
