Deep Black: Payback: Word is out to ex-Marine sniper Charlie Dean and his team of the National Security Agency: Infiltrate the highest stratum of Peruvian political power and derail a renegade general from acing an election. All Dean has to do is find a way inside an impenetrable bank vault protected by armed guards round the clock - it's all in a day's work for the men and women of Deep Black. But things get complicated when Dean and company discover the renegade general's second plot - a nuclear weapon he claims is in the hands of Marxist guerillas. Deep Black: Jihad: The world's most effective anti-terrorist force has the tools to monitor every move the enemy makes. They've planted a listening device inside a terrorist's skull, and activated a video spy drone disguised as a bird. But knowing is only half the battle... Multi-lingual, nerves-of-steel agents Charlie Dean, Lia DeFrancesca, and Tommy Karr prowl the winding streets of Istanbul to the crowded airports of America to stop terrorists in their tracks. Deep Black: Conspiracy: A Secret Service agent is dead, an apparent suicide. A presidential candidate narrowly escapes an assassin's bullet. And Desk Three, a covert branch of the NSA, is searching for a chilling connection deep inside the Republic of Vietnam. Once, Charlie Dean was a Marine sniper in Quang Nam Province. Today he's a Deep Black operator, returning to Vietnam to find the source of some threatening e-mail. Instead, he comes face to face with a man he once hunted down...and thought he had killed.
