The Exile

Description for THE EXILE by Allan Folsom:

The Los Angeles Police Department's famed 5-2 squad boards a commuter train in an attempt to take a cold-blooded killer into custody. John Barron, the newest and youngest member of the elite LAPD unit, learns quickly that the 5-2 has their own deadly system of justice, and that even the slightest protest will result in his suffering the same swift fate. Thus begins a dark, explosive struggle between good and evil―pitting Barron's squad against an exceedingly imaginative and brutal killer.

Suddenly the game widens when John flees to London with his sister, Rebecca, and they are thrown into a race against time. Pursuing them is a baroness, beautiful and cruel, who will stop at nothing to protect her family, her fortune, and her global ambitions. Her secret―spanning oceans, continents, the collapse of the USSR, even the death of the Tsars―is a stunning revelation that could catapult her to the pinnacle of world power.
