Mary Higgins Clark, known as the Queen of Suspense for her page-turning crime novels, has died at the age of 92, the Washington Post reported Friday. Clark did not begin her fiction career until she was in her 40s, but she was an instant hit with the first of dozens of books, Where Are the Children? A $64 million contract for five books, inked in 2000, made her the highest-paid woman writer in the world.
