The Black Dahlia (2006 film)
Through the investigation of the Dahlia's murder, Bucky learns that Elizabeth liked to hang out with "sisters" (what lesbians were described in the 1940's). He goes to a lesbian nightclub and meets Madeleine Linscott (Hilary Swank), who looks very much like Elizabeth. Madeleine, who comes from a prominent family, tells Bucky that she was 'very close' with Elizabeth but asks him to keep her name out of the papers. In exchange for his silence, she promises him sexual favors. Continuing his relationship with Madeleine, Bucky meets her wealthy parents, Emmett (John Kavanagh) and Ramona (Fiona Shaw).

Furious with Lee and Kay for their actions and lies, Bucky returns to Madeleine's family mansion and continues his intense relationship with her. Kay is furious when she discovers the relationship, especially with the fact that Madeleine bears a striking resemblance to the deceased girl Lee obsessed over before was killed and leaves the scene.

Watching an old movie one night, Bucky notices that a bedroom scene matches the set in Elizabeth's pornographic movie. The credits at the end of the film includes the statement "Special Thanks to Emmett Linscott", Madeleine's father. Bucky's search for answers leads him to an incomplete housing project that Madeleine's father had started just below the Hollywoodland sign. In one of the empty houses, Bucky recognizes the set that was used to film Elizabeth's pornographic movie. In a barn on the property, Bucky finds where Elizabeth was killed and her body butchered, as well as a drawing of a man with a Glasgow smile. The drawing resembles a painting in Madeleine's family home and matches the disfiguring smile carved into Elizabeth's face during her murder.

Bucky confronts Madeleine and her father in their home, accusing them of murdering Elizabeth. Madeleine's mother Ramona reveals that she was the one to kill Elizabeth, who looked so much like Madeleine. She confesses first that Madeleine was not fathered by Emmett but rather by his best friend, George, whom she had an affair with. She further reveals that George had been on set when Elizabeth's pornographic film was made, becoming infatuated with her. Finally, she felt that Elizabeth looked too much like Madeleine, was bothered that George was going to have sex with someone who looked like his own daughter, and decided to kill Elizabeth first. Upon finishing her confession, Ramona kills herself.

A few days later, remembering something Lee had said during the investigation, Bucky visits Madeleine's sister Martha with some questions. He learns that Lee knew about the lesbian relationship between Madeleine and Elizabeth and was blackmailing Madeleine's father to keep it secret. Bucky finds Madeleine at a seedy motel, and she admits to being the shadowy figure who slit Lee's throat. Although she insists that Bucky wants to have sex with her rather than kill her, he tells her she is wrong and shoots her dead.
