The Good Killer by Harry Dolan
Sean is at a shopping mall when Henry Alan Keen, scorned by a woman he's been dating, pulls out a gun and begins shooting everyone in sight. A former soldier, Sean rushes toward Keen and ends the slaughter with two well-placed shots - becoming a hero with his face plastered across the news.
But this new-found notoriety soon exposes him to the wrath of two men he thought he had left safely in his past. One blames Sean for his brother's death. The other wants to recover a treasure that Sean and his partner Molly stole from him. Both are deadly and relentless enemies, and Sean and Molly will need to draw on their strength and devotion to each other if they hope to elude them.
Thus begins a cross-country chase that leads from Texas to Montana, from Tennessee to New York to Michigan, as the hunters and their prey grow ever closer.
A wickedly clever and exhilarating thriller, The Good Killer offers a sophisticated, breathtaking look at the extremes people will reach for love, greed, and survival.
