The Cabal - David Hagberg

CIA operative Todd Van Buren meets with Joshua Givens, a "Washington Post" investigative reporter who has uncovered a dangerous secret. Givens suspects that a lobbyist has formed a shadowy group called the Friday Club, whose members come from the White House, the Pentagon, Homeland Security, the FBI, and even the CIA. The journalist is convinced that the cabal is powerful enough to topple the United States . . . and he's terrified.

That afternoon, Van Buren son-in-law of legendary spy Kirk McGarvey is gunned down. That evening, Givens and his family are killed. Anything that might reveal the existence of the Friday Club is destroyed.

A devastated McGarvey is about to be drawn into the most far-reaching and perilous investigation of his career, one that could paralyze the government and shake the foundations of the world financial order."
