Circle of Steel — Don Pendleton

UNDER THE GUN
A ruthless army of renegade mercenaries, led by a Vietnam veteran, joins forces with international assassins to expand their U.S.-based arms-dealing operation.

But the ex-soldier's reputation for deception and double cross finally jeopardizes his fledgling empire -- a former ally wants out, and turns to Mack Bolan for help.

Trafficking in illegal arms is a grim and deadly game, but Bolan has anted up. The Executioner is about to play out his own deadly hand.
