Sulfur Springs

Cork O'Connor and his new wife Rainy Bisonette get a call from her estranged son Peter: he has killed a man named Rodriguez, and then the line goes dead.

They drive south to Sulfur Springs, a desert town on the Arizona–Mexico border, and find that Peter lost his counselling job months ago and no one will admit to knowing where he is. The Rodriguez family runs everything that crosses the border here, and every person Cork asks — the sheriff, the ranchers, the volunteers leaving water in the desert — is lying to him about something.

Sulfur Springs is the sixteenth Cork O'Connor novel, and the one that takes Cork furthest from home: out of the northern woods and into a landscape where the moral lines he trusts do not hold.
