River's End by James Oliver Curwood was originally published in 1919. It is a mystery/thriller story set in the Canadian wilderness. An alleged criminal, Keith, is pursued by a Mountie, Conniston, into the Northern territories. Eventually, Keith is captured but Conniston takes ill. Before Conniston succumbs to death, he and Keith form a friendship. Conniston suggests that Keith assume his identity so that he can return to a normal life. Keith does this and returns home. Will he be recognized? Will he be able to clear his name?
The book is an interesting and exciting read. There are a few things that are particular to the time it is was published. There is one characterization that is not politically correct by today's standards. There are a few other things that I found confusing, especially Keith's relationship to Conniston's sister. Still, it is interesting to read. The story could certainly be updated and still retain the author's intents.
