The Mystery of the Moonlight Murder:

Murder and mystery on the Canadian prairies! August, 1908. One hundred years ago, under the light of a full moon, 12-year-old John Diefenbaker and his younger brother, Elmer, are nearby when their neighbour is shot to death in a field. The murder in small-town Saskatchewan ignites a desperate search for the killer by the Royal North West Mounted Police. 
When a family friend of the Diefenbakers is arrested for the murder, a man from a Plains Cree band, John is certain they have the wrong person. With the help of the man’s 11-year-old daughter, Summer Storm, John and Elmer set out to prove his innocence. But with only five days left before the murder trial, time is running out.
Meanwhile a charismatic Metis man named Andre Dumont, claiming to be related to the famous military commander Gabriel Dumont, is trying to stir up anger against the federal government. The last thing the police need is another full-scale rebellion on their hands.From a smooth-talking Rawleigh’s salesman, to a testy general store owner, to mysterious strangers…all is not what it seems. See how these colourful characters not only challenged the Canadian west but also the sense of justice and fairness in a young boy who would one day lead the nation.
