In a lonely canyon high above El Paso, a ruthless millionaire and a hardline socialist live side by side. Raymond Dwight makes money mercilessly and Leslie Young hates the rich with a passion, but the men have coexisted peacefully — so far. But when Western novelist Asa Baker escapes to Young's cabin for a weekend of writing, he can sense tension in the air. His friend has always muttered about tossing a few bombs at Dwight's estate, but his jokes have stopped being funny. Baker has seen enough bloodshed to know that there is murder on the horizon.
When he finds Young dead on the floor, a strange mark on his cheek, Baker calls the only man who can help: Jerry Burke, the toughest cop in El Paso. In the shadowy corners of this Texas canyon lie secrets that someone will kill to protect — and Burke is the only man daring enough to uncover the truth.
