When a wolf leaves the pack, he lives only as long as he can kill by himself quicker and surer than any pack he runs up against. Meet a man beyond either forgiveness or vengeance. Meet the Man they Call The Lone Wolf. Better meet him now. The way he lives, he can’t live much longer. After Wulff killed Carlin in Mexico City and watched his dynamited house burn down, he decided he deserved a rest. He knew that his work wasn’t nearly over. But a lot of the top men were down . . . bullet-riddled, blown up or cremated, and the organization was beginning to feel the effect. Wulff could relax . . . a day or two at least. What he didn’t know was that little vacation in Mexico city would touch off the most violent, far-ranging hunt of his life, a Killing Run that would take him across two countries, his mad fury for vengeance almost consuming him as well.
