James Myers Thompson (September 27, 1906, Anadarko, Oklahoma Territory - April 7, 1977, Los Angeles, California) was a United States writer of novels, short stories and screenplays, largely in the hardboiled style of crime fiction.

Thompson wrote more than thirty novels, the majority of which were original paperback publications by pulp fiction houses, from the late-1940s through mid-1950s. Despite some positive critical notice, notably by Anthony Boucher in the New York Times, he was little-recognized in his lifetime. Only after death did Thompson's literary stature grow, when in the late 1980s, several novels were re-published in the Black Lizard series of re-discovered crime fiction.

Thompson's writing culminated in a few of his best-regarded works: The Killer Inside Me, Savage Night, A Hell of a Woman and Pop. 1280. In these works, Thompson turned the derided pulp genre into literature and art, featuring unreliable narrators, odd structure, and surrealism. A number of Thompson's books became popular films, including The Getaway and The Grifters.

The writer R.V. Cassill has suggested that of all pulp fiction, Thompson's was the rawest and most harrowing; that neither Dashiell Hammett nor Raymond Chandler nor even Horace McCoy, author of the bleak They Shoot Horses, Don't They?, ever "wrote a book within miles of Thompson".[1] Similarly, in the introduction to Now and on Earth, Stephen King says he most admires Thompson's work because "The guy was over the top. The guy was absolutely over the top. Big Jim didn't know the meaning of the word stop. There are three brave lets inherent in the forgoing: he let himself see everything, he let himself write it down, then he let himself publish it."[2]

Thompson admired Fyodor Dostoevsky and was nicknamed "Dimestore Dostoevsky" by writer Geoffrey O'Brien. Film director Stephen Frears, who directed an adaptation of Thompson's The Grifters as 1990's The Grifters, also identified elements of Greek tragedy[3] in his themes.

Lou Ford is the deputy sheriff of a small town in Texas.The worst thing most people can say against him is that he's a little slow and a little boring.But, then, most people don't know about the sickness --the sickness that almost got Lou put away when he was younger.The sickness that is about to surface again.

An underground classic since its publication in 1952, The Killer Inside Me is the book that made Jim Thompson's name synonymous with the roman noir .
