Assault Force by Don Pendleton

ARMED INTERVENTION

When a hotel in Barcelona comes under siege by religious fanatics, innocent guests are suddenly caught in a nightmare to be played out on the world stage. The situation is unraveling fast amid the mounting chaos of blood and fear—even as an American hostage waits for his chance to turn the tide of slaughter.

Mack Bolan knows what his captors are capable of; he has stared many times into the rabid eyes of zealots and witnessed the fires of commitment to a warped cause. Judging by the seamless takedown of the premises, he realizes he's up against consummate professionals who are ready for anything and will stop at nothing. But the enemy has made a fatal mistake: They let the Executioner live.
