Triangle of Deception — Haggai Carmon

How do you penetrate the world's most secretive and tightly knit terrorist organization? Dan Gordon's only option is deception. Working undercover in a joint CIA/Mossad mission, he's on the hunt for the source of funding to Hezbollah. He has infiltrated a Lebanese network in Paraguay, only to realize the operation is far more wide-ranging than he's been told.

And when Dan finds himself locked in a grim Romanian prison cell, he wonders if there's still more that he hasn't been told. Was it a security leak that got him arrested? Did the CIA make him a sacrificial lamb? Or has he stumbled on a much bigger plot, one with the potential to disrupt Al Qaeda's operations in America?
