Though it's not readily obvious from the title, Lumberjack is the 52nd entry in the long-running "Hopalong Cassidy" series. In this one, Hoppy (William Boyd) and his pals California (Andy Clyde) and Jimmy (Jimmy Rogers) come to the rescue of recently widowed Julie (Ellen Hall). It so happens that Julie has fallen heir to a valuable spread of timber property, meaning that any one of her business rivals could have been the murderer of her husband. Not only does Hoppy reveal the killer's identity, but he also moves heaven and earth to make sure that Julie's mortgage-lifting lumber shipment arrives at its destination on time.
