Nebraska night riders

Skye Fargo's making his way across Nebraska when he comes upon a burning cabin, and an entire family shot execution-style. He soon learns that there's a killer on the loose: smallpox. But a threat worse than the disease is terrorizing the plains. They're called night riders, and they're out to make sure that anyone with smallpox--and those near them--doesn't live long enough to spread the illness. Now the Trailsman is going to give the cowardly killers a dose of their own medicine.
