The Canyon - Dyer Wilk - Bog

They're not bad men. They just do bad things. And when they find themselves trapped at the bottom of a canyon after a stage coach robbery goes horribly wrong, they quickly realize it's more than just bad luck. The path out has been destroyed by a rockslide, and more than half of them are injured. Their horses are dead, and food is in short supply. And then there's the man up on the rocks with a rifle. Watching them. Waiting for them to go mad and starve.
