In the years resulting in the 9/11 attacks, no single agent of al Qaeda was more successful in compromising the U.S. intelligence community than Ali Mohamed. A former Egyptian military captain, Mohamed succeeded in infiltrating the CIA in Europe, the Green Berets at Fort Bragg, as well as the FBI in California-even as he helped to orchestrate the al Qaeda advertising campaign of terror that culminated in 9/11.

Mainly because investigative reporter Peter Lance demonstrates with this gripping narrative, mature U.S. law enforcement about Triple Cross: How Bin Laden’s Master Spy Penetrated the CIA, the Green Berets, and the FBI officials-including the now-celebrated U.S. lawyer Patrick Fitzgerald, who individually interviewed Mohamed a long time before he was taken to ground-were powerless to stop him. In the history of espionage, few men have moved between your hunters as well as the hunted with as very much audacity as Ali Mohamed. For almost two decades, the former Egyptian military commando succeeded in living a increase life. Brazenly slipping past view lists, he relocated in and from the U.S. with impunity, marrying an American girl, becoming a naturalized resident, and posing as an FBI informant-all while acting as key of security for Osama bin Laden and Ayman Al-Zawahiri. Known to his fellow terrorists as Ali Amiriki, or “Ali the American,” Mohamed gained access to one of the most sensitive intelligence in the U.S. counterterrorism arsenal while brokering terror summits, planning bombing missions, and teaching jihadis in bomb building, assassination, the creation of sleeper cells, and additional works of espionage.

Building in the analysis he first chronicled in his previous books, 1000 Years for Revenge and Cover Up, Lance uses Mohamed to trace the untold story of al Qaeda’s rise in the 1980s and 1990s. Extremely, Mohamed, who remains in custodial witness protection today, has never been sentenced for his offences. He exists under a veil of secrecy-a living see to the way the U.S. intelligence community was outflanked for a long time from the terror network. From his first appearance on the FBI’s radar in 1989-teaching Islamic extremists on Long Island-to his existence in the database of Operation Able Danger eighteen weeks before 9/11, this devious triple agent was the one terrorist they had to sweep beneath the rug.

Filled with news-making revelations, Triple Cross exposes the incompetence and duplicity from the FBI and Justice Department before 9/11 . and increases serious questions about how many more secrets the Feds may be hiding.
