John Slocum is a basically decent man who will do whatever it takes to survive what life in the Western Frontier throws at him.
Slocum's adventures have taken him over a lot of the West. He has been a soldier, slave, stage driver, shotgun guard, bank robber, lawman, pioneer, cowboy, sheepherder, poor man, rich man, gambler, and drifter.
The books are adult oriented; in fact, they were first published by Playboy press.
At least one title (Ride for Revenge) was written by Martin Cruz Smith.
