|Cause of Death||
Lucy Westenra is London's sexy, social butterfly with a penchant for gossip, flirting and all things glamorous. She is the daughter of the late Minerva Westenra, the ex-girlfriend of Alastair Harvey, and the ex-best friend of Mina Murray.
Lucy is closer to none other than her best friend Mina Murray. Lucy is extremely beautiful and has captured the eyes of many men, however Lucy always acts disinterested. Lucy introduces Mina to the dregs of low society, taking her to drug dens and so forth. It soon becomes obvious that Lucy is in love with her best friend Mina. When she admits her true feelings to Mina, Mina is repulsed. Lady Jayne Wetherby gives lessons of love to the devastated Lucy in order to manipulate her and convinces her to seduce Jonathan. She succeeds and they sleep together. After this, she feels guilty and confesses to Mina. Mina tells Alexander who in anger that Lucy could hurt Mina like that, transforms her into a vampire. She then bites (and possibly turns) her mother, Minerva.
