Every man has his dark side . . . Spero Lucas confronts his own in the most explosive thriller yet from one of America's best-loved crime writers.

The job seems simple enough: retrieve the valuable painting -- 'The Double' -- Grace Kinkaid's ex-boyfriend stole from her. It's the sort of thing Spero Lucas specializes in: finding what's missing, and doing it quietly. But Grace wants more. She wants Lucas to find the man who humiliated her -- a violent career criminal with a small gang of brutal thugs at his beck and call.

Lucas is a man who knows how to get what he wants, whether it's a thief on the run -- or a married woman. In the midst of a steamy, passionate love affair that he knows can't last, in pursuit of a dangerous man who will stop at nothing to get what he wants, Lucas is forced to decide what kind of man he is -- and how far he'll go to get what he wants.
