Ellroy has become known for a so-called "telegraphic" prose style of his most recent work, wherein he frequently omits connecting words and uses only short, staccato sentences.For instance:
They sent him to Dallas to kill a nigger pimp named Wendell Durfee. He wasn't sure he could do it. The Casino Operators Council flew him. They supplied first-class fare. They tapped their slush fund. They greased him. They fed him six cold.
Other hallmarks of his work include dense plotting and a relentlessly pessimistic—albeit moral—worldview. His work has earned Ellroy the nickname the "Demon Dog of American crime fiction."
Ellroy writes longhand on legal pads, rather than on a computer, and prepares elaborate outlines for his books, most of which are several hundred pages long.
Dialog and narration in Ellroy novels often consists of a "heightened pastiche of jazz slang, cop patois, creative profanity and drug vernacular", with a particular use of period-appropriate, but now anachronistic, slang. He often employs stripped-down staccato sentence structures, a style that reaches its apex in
The Cold Six Thousand, and which Ellroy describes as a "direct, shorter-rather-than-longer sentence style that's declarative and ugly and right there, punching you in the nards." This signature style is not the result of a conscious decision, but chance. This came about when he was asked by his editor to shorten his novel "White Jazz" from 900 pages to 350. Rather than removing any sub-plots, Ellroy achieved this by eliminating verbs, creating a unique style of prose. While each sentence on its own is simple, the cumulative effect is a dense, baroque style.
The L.A. Quartet
While his early novels earned him a "cult" following, Ellroy earned much greater success and critical acclaim with the L.A. Quartet...
The Black Dahlia,
The Big Nowhere,
L.A. Confidential, and
White Jazz. The four novels represent Ellroy's change of style from the tradition of classic modernist noir fiction of his earlier novels to so-called postmodern historiographic metafiction.
The Black Dahlia, for example, fused the real-life murder of Elizabeth Short with a fictional story of two police officers investigating the crime.
Underworld USA Trilogy
In 1995, Ellroy published
American Tabloid, the first novel in a series informally dubbed the "Underworld USA Trilogy", which Ellroy describes as a "secret history" of the mid-to-late 20th century.
Tabloid was named
TIME's fiction book of year for 1995. Its follow-up,
The Cold Six Thousand, became a bestseller. The final novel,
Blood's a Rover, was released on September 22, 2009.
My Dark Places
After publishing
American Tabloid, Ellroy began a memoir,
My Dark Places based on his memories of his mother's murder and his investigation of the crime. In the memoir, Ellroy mentions that his mother's murder received little news coverage, and the media was still fixated on Johnny Stompanato's murder. Frank C. Girardot, a reporter for
The San Gabriel Valley Tribune, accessed files on Geneva Hilliker Ellroy's murder from detectives with Los Angeles Police Department. Based on the cold case file, Ellroy and investigator Bill Stoner worked the case, but gave up after fifteen months, believing any suspects to be dead. In 2008, The Library of America selected the essay "My Mother's Killer" from
My Dark Places for inclusion in its two-century retrospective of American True Crime.
