Biography
As a child, Amy Elliot Dunne was the inspiration for her parents to create Amazing Amy, a series of popular children's books. The character Amazing Amy put tremendous pressure on the real-life Amy, who tried to live up to the seemingly flawless version of herself that her parents created.

Later in life, she met Nick Dunne at a party, who is a writer like she is. They quickly hit it off and begin a relationship, becoming married shortly after. Their marriage is going great until the 2008 recession, causing them both to lose their jobs. On top of that, her parents request a large sum of money that nearly drains their bank accounts, putting their marriage on the rocks. At the height of all of this, Nick's mother is diagnosed with Stage 4 breast cancer, forcing Nick and Amy to move from their townhouse in New York to a home outside of St. Louis, Missouri, where Nick gets a job as a creative writing teacher.

After the death of Nick's mother, Nick and Amy's relationship continues to decline, Nick only seeming to give Amy attention when they are having sex. After purchasing a bar for him, she later finds Nick with Andie, a student of his. After realizing that she is being cheated on, she puts her grand scheme into motion.

She begins by befriending a neighbor Noelle, whom Amy deems "the town idiot." She later begins to purchase many expensive electronics with credit cards she put in Nick's name, writes bogus diary entries that exagerate and fabricate Nick's physical abuse towards her and her fears of him murdering him, and fakes pregnancy by stealing Noelle's urine. On the night before Nick and Amy's anniversery (where Nick was going to ask Amy for a divorce), she plans a scavenger hunt with objects connected to his betrayal (the diary (which she partially burns in the furnance of Nick's father's home), a pair of Andie's panties, and the electronics with a box containing a Punch and Judy puppet set). The next morning, she sets up her faked murder, rigging the house to imply a struggle and quick coverup, drawing her own blood that she spills on the kitchen floor and mopping it up, and putting her blood on a blunt object which she burns in their fireplace.

By the time Amy leaves, Nick discovers and reports her disappearance, the neighbors (namely Noelle) and authorities suspecting Nick in her murder, causing him to be crucified on national TV and the authorities seeking the death penalty (which exists in Missouri).

Meanwhile, Amy drastically changes her appearance and starts a new life as "Nancy," drawing thousands of dollars in cash to support herself. She later meets her new neighbors, Greta and Jeff, who don't suspect a thing about her or her previous life. One night, Greta and Nick catch Amy with her money, prompting them to break into her house and violently rob her, leaving her penniless.

She then comes into the reaquaintance of Desi Collings, a wealthy former boyfriend of hers who has grown obsessed with her. Knowing he faked her death, he takes her into his lavish home nonetheless and promises to keep her safe and be a good lover.
