Elmore Leonard, the prolific crime novelist whose louche characters, deadpan dialogue and immaculate prose style in novels like “Get Shorty,” “Freaky Deaky,” “Glitz” and “La Brava” secured his status as a modern master of American genre writing, died Tuesday at his home in Bloomfield Village, Mich. He was 87.

His death was announced on his Web site.

To his admiring peers, Mr. Leonard did not merely validate the popular crime thriller; he stripped the form of its worn-out affectations, reinventing it for a new generation and elevating it to a higher literary shelf.

Reviewing “Riding the Rap” for The New York Times Book Review in 1995, Martin Amis cited Mr. Leonard’s “gifts — of ear and eye, of timing and phrasing — that even the most indolent and snobbish masters of the mainstream must vigorously covet.” As the American chapter of PEN noted, when honoring Mr. Leonard with its Lifetime Achievement award in 2009, his books “are not only classics of the crime genre, but some of the best writing of the last half-century.”

Mr. Leonard’s first story was published in Argosy magazine in 1951, and 60 years later he was still turning out a book a year because, he said, “It’s fun.”

It was in that spirit that Mr. Leonard, at 84, took more than a casual interest in the development of one of his short stories, “Fire in the Hole,” for television. “Justified,” as the FX series was called, won a Peabody Award in 2011 in its second season and sent new fans to “Pronto” (1993) and “Riding the Rap” (1995), two novels that feature the series’s hero, Raylan Givens (played by Timothy Olyphant), a federal marshal from Harlan Country, Ky., who presents himself as a good ol’ country boy but is “not as dumb as you’d like to believe.”

Approving of the way the show was working out, Mr. Leonard wrote his 45th novel, “Raylan,” with the television series in mind. Published in 2012, it featured three strong female villains and gave its cowboy hero license to shoot one of them.

Acknowledging his approval of “Justified” was a major concession for Mr. Leonard, who was candidly and comically disdainful of the treatment his books generally received from Hollywood, even commercially successful films like “Get Shorty,” “Be Cool” and “Out of Sight.” His first novel, “The Big Bounce,” was filmed twice, in 1969 and 2004. After seeing the first version, he declared it to be “at least the second-worst movie ever made.” In a much-told anecdote, he said that once he saw the remake, he knew what the worst one was.

In an interview with Doug Stanton for the National Writers Series in Traverse City, Mich., in 2011, Mr. Leonard succinctly explained why “Get Shorty,” the 1995 movie starring John Travolta was a faithful treatment of his novel of the same name, and why its sequel, “Be Cool,” was not. The directive he had given the producers about his clever crooks — “These guys aren’t being funny, so don’t let the other characters laugh at their lines” — was, he said, heeded in the first case and ignored in the second.
