The Killer Inside Me characters

Appears from the start

A deputy sheriff in a small West Texas oil town. Lou presents himself as slow, courteous, and harmless, often boring people with clichés until they dismiss him. His private narration reveals a calculating man who experiences violent compulsions and uses his respectable position to study, deceive, and control those around him.

Appears from the start

A prostitute living outside town whom Lou is ordered to move along. Joyce is defiant when he arrives and quickly recognizes violent desires beneath his mild public manner.

The town sheriff and Lou's superior. Maples trusts Lou's familiar, unthreatening manner and relies on him as a steady deputy.

First appears in chapter 3

Lou's longtime fiancée, a conventional and socially respectable young woman who expects them eventually to marry. Amy is affectionate but strong-minded, and her familiarity with Lou makes her harder to mislead than the townspeople who know only his public persona.

The son of wealthy construction businessman Chester Conway. Elmer is having a secret relationship with Joyce and wants to escape his father's control.

First appears in chapter 9

A young man in town whom Lou treats with apparent friendliness and small favors. Johnnie trusts the deputy and has little social power of his own.

First appears in chapter 12

A county prosecutor who looks past Lou's deliberately dull manner. Hendricks approaches inconsistencies patiently, allowing Lou to believe he remains in control while testing the stories surrounding the recent deaths.
