Since the copyright has expired on these books, they are now available on the net. Guess what? I have found a place that allows you to read all the Oliver Strange books online.James Green aka Sudden is a fictional character created by the author Oliver Strange and after his death carried on by Frederick H. Christian. The books are centred around a gunfighter in the American Wild West era, who is in search of two men who cheated his foster father. Jim the young man promises his dying father that he will find the two and take revenge. He gives the name James Green to himself and in time gets accused of a robbery himself and becomes an outlaw.
The books were first published around the late 1920s and the early 1930s. They featured vivid descriptions of the western American landscape, rare in an author at that time. These book have been out of print for a very long time, and are currently available for purchase only in paper format, after being owned by one of more people.
