The Book of Daniel (1971) is semi-historical novel by E. L. Doctorow, loosely based on the lives, trial and execution of Ethel and Julius Rosenberg. Doctorow tells the story of Paul and Rochelle Isaacson (corollaries to the Rosenbergs) through the persons of their older son, Daniel, and his sister, Susan, who are college students deeply involved in 1960s politics.
