X is an identity thief extraordinaire who steals the identity of the worst possible person! He soon becomes a fugitive, hunted by every intelligence agency in the world. The international adventures of this sardonic and amoral anti-hero combine the irony of The Third Man with the fast-paced thrills of The Bourne Identity.

To survive, X must use his talent for deceit and his chameleon-like ability to adopt one persona after another, as his predicament becomes steadily more harrowing and the stakes mount.
