Tom Clancy, a best-selling author of spy and military thriller novels such as "The Hunt For Red October" and "Clear and Present Danger," which were made into films, has died at age 66.

The writer passed away in Baltimore -- where he was born -- on Tuesday, Oct. 1, publishing company Penguin Group announced on Wednesday in a statement obtained by OTRC.com. The cause of his death was not made public. The news comes more than two months before the release of his 17th novel, "Command Authority," which is set to hit stores on Dec. 3.

"The Hunt For Red October" was Clancy's first published novel and was released in 1984. In a 1990 film based on the book, Alec Baldwin played CIA analyst Jack Ryan. Sean Connery portrayed a respected Soviet naval captain named Marko Ramius. "The Hunt For Red October" won an Oscar for its sound effects editing.

"Rest in peace the great writer Tom Clancy. A real gentleman of the old school," Baldwin tweeted on Wednesday.

Harrison Ford played Ryan in the 1994 film adaptation of "Clear and Present Danger" as well as in another movie based on a Clancy novel -- "Patriot Games."
