The Sky Pilot in No Man's Land

Canadian novel, first published in 1919. According to Wikipedia: "Rev. Dr. Charles William Gordon, or Ralph Connor, (September 13, 1860 October 31, 1937) was a Canadian novelist, using the Connor pen name while maintaining his status as a Church leader, first in the Presbyterian and later the United churches in Canada. Gordon was also at one time a master at Upper Canada College. He sold more than five million copies of his works in his lifetime,[1] and some of his works are still in print.... Gordon became interested in writing during his student days at the University of Toronto. He published his first novel, Black Rock, in 1898. While the book was moderately successful in Canada, his second novel, The Sky Pilot, gained him international attention in 1899 and sold more than 1,000,000 copies. The Sky Pilot, like many of his works, was a frontier adventure with strong themes of morality and justice. He continued to write until his death in 1937."
