Question: I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: The Girl with the Dragon Tattoo Movie plot: In December 2002, Mikael Blomkvist, publisher of Millennium magazine, loses a libel case involving allegations he published about billionaire financier Hans-Erik Wennerstrom. He is sentenced to three months in prison and a hefty fine. Lisbeth Salander, a brilliant but damaged surveillance agent and hacker, is hired by Henrik Vanger, the patriarch of the wealthy Vanger family, to investigate Blomkvist. Vanger then hires Blomkvist to investigate the disappearance of his niece, Harriet, who vanished on Children's Day in 1966. Vanger believes that Harriet was murdered by a family member. Salander, who was ruled mentally incompetent as a child, is appointed a new legal guardian, Nils Bjurman, after her previous guardian suffers a stroke. Bjurman, a sexual sadist, forces Salander to perform fellatio on him in return for the money she needs to buy a new computer; he withholds the full amount she has requested. At her next meeting with Bjurman, he beats and rapes her. Having used a hidden camera to record Bjurman raping her, Salander returns to take her revenge, torturing and threatening to ruin him unless he gives her full control of her life and finances. She then uses a tattoo gun to brand Bjurman's abdomen with the message "I am a sadist pig and a rapist". Blomkvist moves to a cottage on the Vanger estate and meets the Vanger family, including Harriet's brother Martin and cousin Cecilia. Inside Harriet's diary, he finds a list of five names alongside what might appear to be phone numbers. He visits retired police inspector Morell, who informs him that his investigation team had been unable to decipher them. After viewing photographs taken during the Children's Day parade, Blomkvist sees Harriet's facial expression change suddenly just before she leaves and, after obtaining photographs taken from the same side of the street as her, comes to believe that Harriet may have seen her murderer that day. Using her access to Blomkvist's computer, Salander learns that the numbers in Harriet's diary are references to... My question: Who is Cecilia's late sister?
