As a professional 'cleaner', Jonathan Quinn disposes of bodies and ties up loose ends. Doesn't get his hands dirty, no wet work. But when he discovers he's been hired to vanish all traces of Steven Markoff, one of his best friends who just happened to work for the CIA, his job suddenly hits too close to home. This time, it's personal. Quinn is determined to get justice for Markoff. Plus, now, Markoff's girlfriend Jenny, who had been an assistant to an ambitious Congressman, has also disappeared. Racing from the corridors of power in Washington to the bustling streets of Singapore - along with his smart, eager apprentice Nate and brilliant, beautiful Orlando, his closest friend who's saved his life more than once - events quickly spiral dangerously out of control. With an addictive momentum and fascinating characters, "The Deceived" takes us on a thrilling, nerve-wracking journey.

Shadow of Betrayal

by Brett Battles

Published 1 January 2009
Three jobs, no questions. That’s the deal Jonathan Quinn—freelance operative and professional “cleaner”—has struck with his client at the Office. But his first assignment in rural Ireland unexpectedly results in four dead bodies to dispose of—and leads him to an astounding mystery about to spin wildly out of control.

Now Quinn, along with his colleague and girlfriend, the lethal Orlando, has a new mission: find and protect a U.N. aide worker who has suddenly disappeared from her assignment in war-torn Africa. If it were only that easy. Soon Quinn and Orlando will unearth a horrifying plot that is about to reach stage critical for a gathering of world leaders—and an act of terror more cunning, and more insidious, than anyone can foresee.

Book 4

The Silenced

by Brett Battles

Published 1 January 2011
“A complex, action-packed international cat and mouse game.”—New York Times bestselling author John Lescroart

Professional “cleaner” Jonathan Quinn has a new client and an odd job: find and remove the remains of a body hidden twenty years ago inside the walls of a London building, before the building is demolished.

But Quinn and his team are being watched. Suddenly caught in the cross fire between two dangerous rivals, Quinn must unravel the identity of the body and why it still poses so great a threat even in death. Because a plot stretching from the former Soviet Union to Hong Kong, from Paris to London, from Los Angeles to Maine, is rapidly falling apart. And Quinn hasn’t been hired just to tie up loose ends—he is one.
