The explosion that shatters the smart Parisian apartment reverberates around the globe. In an instant, a suspected terrorist is dead and half a million dollars has vanished. Within days, the CIA is certain it has found a connection between the dead man and a planned terrorist attack on U.S. soil. Determined to avert another 9/11, they have assembled an elite counterterrorist task force, code name: Blood Money. Its mission: to follow the money trail. Its secret weapon: forensic accountant Adam Chapel. A man who trusts numbers more than people, Chapel has his own reasons for wanting to get the job done - four of his colleagues were killed in the Paris blast. Now Chapel is thrust back into the line of fire when he teams up with British intelligence agent Sarah Churchill. The two are assigned to hunt down a shadowy mastermind who is moving vast sums of money from country to country, from bank to bank, leaving no tracks - as he prepares for an Armageddon of his own devising.

As Chapel follows a disappearing money trail from Paris to Munich to the deserts of Saudi Arabia, Sarah uses her elite training to stalk the "shadow" and his elusive network. Meanwhile, their quarry is auditing their every move, laying a twisting trail of false clues and shocking surprises. With the clock ticking down, soon Chapel and Sarah have only days, hours, minutes to avert disaster as a master terrorist plots to unleash the first strike in a brilliantly orchestrated conspiracy - with an almost unimaginable goal.
