The Wailing Siren Mystery

Blurb

The Wailing Siren Mystery is Volume 30 in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap.
This book was written for the Stratemeyer Syndicate by Andrew E. Svenson in 1951. 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 shortened in 1968 by Priscilla Baker-Carr resulting in two similar stories sharing the same title.
