Asylum-"You think I'm full of shame and regret for what I've done now, Sister? You can shave me bald as a cue ball and I'll still be the hottest tamale in this joint."

Shelley has a bad case of nymphomania. She began masturbating at the age of five. Her mother tried to curb this behavior by forcing her to wear mittens. She felt so happy touching herself that she couldn't stop. Eventually, she ran away to live a fast jazz-filled life and met a bass player whom she eventually married. However, after their happiness died down, her husband expected her to stay at home and be a doting wife while he openly cheated on her with other women. She took revenge by having sex with two Navy sailors, which her husband found. To rid of her, he reported her nymphomania to the authorities and signed to have her locked up in Briarcliff. Like Grace, she proves to be a challenge for Sister Jude, even referred to as the disciplinarian's antagonist.
She is loathed by Dr. Arden, who deems her a whore, as he loves only innocent-like women. However, when he catches her trying to escape during the Nor'easter, he forces her into his office and attempts to rape her, but she laughs when she sees his small penis (possibly mutilated or deformed). In anger, he knocks her out and amputates her legs. She later manages to escape, but when Monsignor Howard finds her, he smothers her and kills her.
