|Appears||Half-Lives: The First Luisa Rey Mystery, Luisa's Mystery|
In the novel, the woman interrupts Smoke long enough for Luisa and Joe to escape. She also helps Luisa and Joe escape through a passage in the sweatshop. She also kills one of Bill Smoke's associates, with a monkey wrench, after he has asked for Luisa and Joe's last words, allowing the pair to escape.
In the film, Bill Smoke kills the woman's dog and calls her a "wetback." While Smoke is trying to chase down Luisa and Joe, the woman sneaks up behind him and beats him to death with a wrench, commenting, "Yo amaba ese perro" (I loved that dog) and "Don't call me a 'wetback.'"
