Flint by Louis L'Amour

He left the West at the age of seventeen, leaving behind a rootless past and a bloody trail of violence. In the East he became one of the wealthiest financiers in America--and one of the most feared and hated.

Now, suffering from incurable cancer, he has come back to New Mexico to die alone. But when an all-out range war erupts, Flint chooses to help Nancy Kerrigan, a local rancher. A cold-eyed speculator is setting up the land swindle of a lifetime, and Buckdun, a notorious assassin, is there to back his play.

Flint alone can help Nancy save her ranch...with his cash, his connections--and his gun. He still has his legendary will to fight. All he needs is time, and that's fast running out....
