Shootout With Death

The prisoner in Sheriff Cook's jail has a warning. Something is coming to the town of Roseshade. Something evil and ancient and deadly. But there is something more, too. There is something mysterious about this prisoner, something in his eyes that suggests a man older than he seems. And the prisoner knows things about Sheriff Glen Cook that no other man should know. And then there's the gun. Sheriff Cook took a gun off the prison that should not exist.
A gun that feels and looks unreal. With the prisoner's warning, Sheriff Cook is left to wonder if he and his prisoner can survive the night. Or will the dawn find them in Death's embrace?
