The Grifters (novel)

At the start of the novel, he gets hit in the stomach with a baseball bat when a simple con goes wrong.

With this knowledge, but mostly because Roy does not want to associate with a person paid by Lilly, he breaks off his relationship with Carol.

Meanwhile, Lilly is at the race track working for an organization headed by gangster Bobo Justus.

Roy goes back to work for the day and meets his new boss Perk Kraggs, who takes a liking to him.

Later, she tells him that they should work together, but he refuses; Moira becomes furious, and Roy slaps her and leaves, thinking that is the end of the relationship.

Lilly pleads with Roy to let her have the money, asking him what she should offer (tempting him to acknowledge his incestuous urge toward her).

Lilly suggests that Roy finish his drink, distracting him and providing the opportunity to hit him with her purse.

The blow accidentally breaks the glass, which cuts into Roy's neck, causing him to bleed to death.

After grasping that she has killed her own son, Lilly promptly regains her composure and leaves with his money.

John Cusack, Annette Bening and Anjelica Huston played the principal roles.
