Blue Pete, the half-breed that now lives near Medicine Hat with his new wife Mira, needs some police work to keep him busy-he cannot rest; it is not in his nature. Inspector Barker of the North-west Mounted Police finally assigns the 'detective' a task that seems too close to Blue Pete's past life to be attractive to him. But Blue Pete has to accept the job-and has to complete his assigned task, even if he has to go back to his U. S. Badlands to complete it (circ. 1910)

A rich American family experiences a theft, and a murder. They set out to capture the criminals---a chase that continues to Europe and Morocco.
