Lightning at the hanging tree

the long version

The rider went by the name of Mike Clancey as this was the name inside his watch, but many people during his travels called him Lightning. He was too late to stop a hanging and the men were far away by the time he reached the lonely swinging figure of a middle-aged man. When a youth arrived on the scene Lightning found out that the hanged man was his father. Why had he been hanged, and why did this youth seem strange? Soon the two were to ride together in a pitiless search for the killers.
