Blurb

The Clue of the Broken Blade is Volume 21 in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap.
This book was written for the Stratemeyer Syndicate by John Button in 1942. 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 1970 by Richard Deming resulting in two different stories with the same title.
