In 1985, a year after the Cold War thriller "The Hunt for Red October" came out, author Tom Clancy was invited to lunch at the Reagan White House, where he was questioned by Navy Secretary John Lehman.
Who, the secretary wanted to know, gave Clancy access to all that secret material?
Clancy, the best-selling novelist who died Tuesday in Baltimore at 66, insisted then, and after, that his information was strictly unclassified: books, interviews and papers that were easily obtained. Also, two submarine officers reviewed the final manuscript.
Government officials may have worried how Clancy knew that a Russian submarine spent only about 15 percent of its time at sea or how many SS-N-20 Seahawk missiles it carried.
But his extreme attention to technical detail earned him respect inside the intelligence community and beyond and helped make Clancy the most widely read and influential military novelist of his time, one who seemed to capture a shift in the country's mood away from the CIA misdeeds that came out in the 1970s to the heroic feats of Clancy's most famous creation, CIA analyst Jack Ryan.
Several of his novels, including "The Hunt for Red October," "Patriot Games" and "Clear and Present Danger," were later made into blockbuster movies, with another, "Jack Ryan," set for release on Christmas.
"Fundamentally, I think of myself as a storyteller, not a writer," Clancy once said. "I think about the characters I've created, and then I sit down and start typing and see what they will do. There's a lot of subconscious thought that goes on. It amazes me to find out, a few chapters later, why I put someone in a certain place when I did. It's spooky."
A tall, trim figure given to wearing sunglasses that made him look like a fighter pilot, Clancy had such a sure grasp of defense technology and spycraft that many readers were convinced he served in the military. But his experience was limited to ROTC classes in college. Nearsightedness kept him out of active duty.
A political conservative who once referred to Ronald Reagan as "my president," Clancy broke through commercially during a tense period of the Cold War, and with the help of Reagan himself.
In 1982, he began working on "The Hunt for Red October," drawing inspiration from a real-life 1975 mutiny aboard a Soviet missile frigate. He sold the manuscript to the first publisher he tried, the Naval Institute Press, which had never bought original fiction.
In real life, the mutiny was put down, but in Clancy's book, a Soviet submarine skipper hands his vessel over to the U.S. and defects.
Someone thought enough of the novel to give it to Reagan as a Christmas gift.
