The worlds of publishing, TV and music have lost three of their contributors. Suspense novelist ROBERT LUDLUM, 73, author of the Jason Bourne series of spy thrillers and "The Matarese Circle," died Monday of an apparent heart attack. "It's a horrible loss for all of his fans and for his publisher," said a spokesman for his publisher, St. Martin's Press . . . Contentious, chain-smoking '80s talk show host MORTON DOWNEY JR., 67, died of lung cancer and other respiratory problems, his family announced Monday night. After his cancer was diagnosed in 1996, and one of his lungs was removed, Downey became an anti-smoking crusader . . . MICHAEL SMITH, 58, the jokester drummer for the '60s rock band Paul Revere and the Raiders, died March 6 in Kona, Hawaii, of natural causes, reports the Associated Press. Raiders' hits included "Just Like Me," "Kicks" and "Indian Reservation."
