Clancy published his first book, “The Hunt for Red October,” in 1984. The novel sold more than five million copies, and became the basis for a hit film starring Alec Baldwin. By 1988, Clancy had netted a $3 million contract with Putnam Penguin Publishing for his next three books.
Though best known for his novels, Clancy began his career working in an independent insurance agency. In 1993, the novelist joined a team of investors to buy the Baltimore Orioles from Eli Jacobs. He remained a part-time owner of the team until his death.
