Jim Thompson's short 1952 novel, "The Killer inside of Me," offers a deeply disturbing portrayal from within the mind of a psychopathic killer, Lou Ford. At 29, Lou narrates his story in the first person. He is a deputy sheriff in the west Texas town of Central City in the 1950s. Lou's mother died when he was young, and he was raised by his physician father and a housekeeper. After his mother's death, when Lou was four, his father adopted a six-year-old orphan, Mike. The story begins six years after Mike's covered-up murder.
The novel starts as Lou investigates, abuses, and falls in love with Joyce, a prostitute. He becomes embroiled in a convoluted blackmail and double-cross. Lou and Joyce are to receive $10,000 from a wealthy construction magnate, Conway, whose profligate son has fallen in love with Joyce and plans to elope with her. Lou has a motive for killing young Conway as his father had arranged for Mike's murder years before. Lou kills Conway and Joyce and attempts to cover his tracks. The novel describes his efforts, further killings, and his growing mental deterioration. It focuses more on Lou's character than on the taut suspense from the murder investigation.
Thompson's novel delves into Lou's tormented, vicious, yet strangely sympathetic character. The residents of Central City see him as "that dull good-natured guy who couldn't do anything bad if he tried." Lou speaks slowly, smiles often, uses many clichés, and appears well-liked. He has a childhood sweetheart, Amy, whom he apparently plans to marry. However, Lou's outward demeanor masks a high intelligence and murderous impulses. He does have a compassionate side, as he befriends a young man, Johnny Pappas, who has a propensity for trouble. But this sympathy doesn't stop Lou from acts of great brutality.
The graphic detail and forethought of Lou's crimes belie his exterior image. His character is developed through reflections on his boyhood. The housekeeper sexually abused him, and he developed a lifelong anger towards women, which he calls "the sickness." His adopted brother Mike served a term in the reformatory after taking the blame for the sexual abuse of a young girl that Lou had committed. Thompson skillfully and convincingly develops Lou's psychopathic character from his early sexual experiences.
Lou's character is also developed through his biting, pithy observations of people and places. For example, when observing mismatched couples, he says, "I've loafed around the streets sometimes, leaned against a store front with my hat pushed back and one boot hooked back around the other -- hell, you've probably seen me if you've ever been out this way -- I've stood like that, looking nice and friendly and stupid, like I wouldn't p.. if my pants were on fire. And all of the time I'm laughing myself sick inside. Just watching the people."
Lou is convinced, with good reason, that his guilt is strongly suspected from the start. His self-understanding increases even as his mind deteriorates. The final sections of the book show a highly demented person, filled with illusions, feelings of guilt, and claustrophobia.
"The Killer Inside Me" is an internalized work that captures a psychotic soul. It served as the basis for films in 1976 and 2010. The author, Jim Thompson (1906-1977), was a prolific writer of noir novels and screenplays. This book is his masterpiece. It is available in paperback or in the Library of America's compilation of five noir novels from the 1950s. This is an excellent novel, regardless of genre.
