The shadow riders

It wasn't asking too much of a man. The Arizona Rangers only wanted Tyrone Cannfield to let himself be thrown into an army punishment camp sentenced to hard labour, escape from the chain gang, track down the Shadow Riders, a gang of plundering, murderous thugs, bring in Mingo, the savage leader of the badmen, and halt a train robbery. All of this to be done on his own with forty badmen ready to shoot him down at the first misstep. It wasn't asking too much of him because Mingo was the man who had murdered Cannfield's wife back in Texas, and he would do everything possible to eliminate him and the Shadow Riders. But would he survive?
