The Book of Daniel 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 through the persons of their older son, Daniel, and his sister, Susan, who are college students deeply involved in 1960s politics.Plot summaryWriting his doctoral thesis, Daniel investigates the background to his parents' conviction and execution with his adoptive parents . The dénouement is the revisiting, in flashback, of the death of his parents, Rochelle and Paul Isaacson, and, in due course, the death from nervous disorder of his sister Susan. The novel closes as the library in which Daniel is working is closed by student protests. Doctorow closes his novel with a parody of lines from Chapter 12 of the Biblical Book of Daniel.The book is written in four parts, and in each Daniel is the principal narrator; the narrative moves fluidly and rapidly between 1967 and flashback, and between first and third person: 1. Memorial Day – Opens, in 1967, with Daniel, his young wife, Phyllis and baby Paul, walking to the sanatorium to see Susan; closes with the dropping of atom bomb in Japan2. Halloween – closes with the lawyer, Ascher, telling Daniel and Susan of the forthcoming start of the Isaacsons' trial3. Starfish – closes with Daniel's bruising involvement in an anti-draft march, while his sister is lying dying from complications following her suicide attempt. Daniel says to Phyllis through broken teeth '...It looks worse than it is. There was nothing to it. It is a lot easier to be a revolutionary nowadays than it used to be.'4 Christmas – recalls the closing moments of the trial, including the key evidence from their co-accused, Selig Mindish; Daniel's later search for, and discovery of Mindish, now senile, in Disneyland; and the funerals of Daniel's parents and his sister Susan.
