The Mystery Of Cabin Island is the eighth volume in the original The Hardy Boys series of mystery books for children and teens published by Grosset & Dunlap. This book was written for the Stratemeyer Syndicate by Leslie McFarlane in 1929. Between 1959 and 1973 the first 38 volumes of this series were systematically revised as part of a project directed by Harriet Adams, Edward Stratemeyer's daughter. The original version of this book was rewritten in 1966 by Anne Shultes resulting in two different stories with the same title.
