The Flickering Torch Mystery is Volume 22 in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap. The book was written for the Stratemeyer Syndicate by Leslie McFarlane in 1943. Between 1959 and 1973 the first 38 volumes of the series were systematically revised as part of a project directed by Harriet Adams, Edward Stratemeyer's daughter. The original version of the book was rewritten in 1971 by Vincent Buranelli resulting in two different stories with the same title.
