Bestselling author Tom Clancy died Tuesday in a Baltimore hospital, his publisher has confirmed. He was 66. Clancy was the author of dozens of military thrillers, including the bestselling Jack Ryan series (including 1987's Patriot Games), whose movie adaptations made millions at the box office. Clancy was born in Baltimore, and he later became a part owner of the Baltimore Orioles. He earned $1.3 million for writing the first Jack Ryan book, The Hunt for Red October, and by 1997 he reportedly earned $50 million for his next two books. He also co-founded the videogame developer Red Storm Entertainment and has had his name on some of Red Storm’s most successful games. His last novel, an installment in the Jack Ryan series titled Command Authority, is scheduled to be published Dec. 3.
