INFO:

Frannie Avery, an introverted writer and English teacher in New York City, meets one of her students, Cornelius, at a local pub to talk about coursework. Cornelius proposes a theory that John Wayne Gacy may not have been guilty of his crimes, later suggesting that 'desire' was responsible. On her way to the basement bathroom, she witnesses a woman performing oral sex on a man. Though it's dark, she can see a 3 of spades tattoo on the man's wrist and the woman's blue fingernails.
