"Gun Cotton, gay and immortal adventurer, goes this time to the little-known principality of Ritzenhausen to rescue his friend, Greville Manning. Greville went on a serious mission - to return to the Prince of Ritzenhausen relics of his son who was killed in the World War - but he finds himself mysteriously side-tracked from seeing the Prince.
"Greville becomes further and further involved by falling in love - then Gun arrives! His friends, who have learned how high-spirited and clever a detective Gun Cotton is, know what to expect. He stumbles upon clues and secret intrigues, has several escapes that are hair-raising in their tenseness, and finds himself caught up in a kidnapping plot that gives the whole story a breezy build-up to an amazing climax."
