The mystery of the death of Ashraf Marwan remains unsolved more than nine years after he plunged to his death from the balcony of his fifth-floor London apartment. But, drawing on once-secret archives and interviews with Israeli intelligence officers, University of Haifa Professor Uri Bar-Joseph has stitched together a riveting story about an Egyptian who betrayed his homeland as a spy for Israel. Bar-Joseph writes that intelligence provided by Marwan at the outset of the 1973 Yom Kippur War helped prevent the fall of the Golan Heights.

University of California President Janet Napolitano will interview Bar-Joseph about his book, the vagaries of intelligence interpretation, and the advantages and disadvantages of human spies vs. electronic espionage. This conversation will be the third in a series of interviews of authors by the former Secretary of Homeland Security.
