First published in 1903, historical novel set during the Civil War, part of the Young Kentuckians Series. The Preface begins: " General John H. Morgan was one of the most picturesque figures in the Civil War, an officer without a peer in his chosen line. During the two years of his brilliant career he captured and paroled at least ten thousand Federal soldiers, and kept three times that number in the rear of the Federal army guarding communications. When we consider the millions of dollars' worth of property he destroyed, and how he paralyzed the movements of Buell, we do not wonder that he was considered the scourge of the Army of the Cumberland. General Morgan was a true Kentucky gentleman, and possessed one of the kindest of hearts. The thousands of persons captured by him almost invariably speak of the good treatment accorded them... The adventures of Calhoun as a secret agent of the "Knights of the Golden Circle" opens up a portion of the history of the Civil War which may be almost unknown to our younger readers. During the war the whole North was honeycombed with secret societies, whose members denounced Lincoln as a usurper and a bloody monster, and maintained that the government had no right to coerce the South."
