The lone FBI Special Agent Mark Andrews. Now, only he knows when the killers will strike. But how can he alone unravel a ruthless conspiracy—in less than one week? The race to save the first woman president begins now…

Not a penny more,  not a penny less 

The conned: an Oxford don, a revered society physician, a chic French art dealer, and a charming English lord. They have one thing in common. Overnight, each novice investor lost his life's fortune to one man. The con: Harvey Metcalfe!!

A brilliant, self-made guru of deceit. A very dangerous individual. And now, a hunted man. 

With nothing left to lose four strangers are about to come together-each expert in their own field. Their plan: find Harvey, shadow him, trap him, and penny-for-penny, destroy him. From the luxurious casinos of Monte Carlo to the high-stakes windows at Ascot to the bustling streets of Wall Street to fashionable London galleries, their own ingenious game has begun. It's called revenge-and they were taught by a master.
