The Sign of the Crooked Arrow is Volume 28 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 1949.[1] 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.[2] The original version of this book was shortened in 1970 by Priscilla Baker-Carr, resulting in two different stories with the same title.
The Hardy brothers interrupt their investigations of jewelry store holdups to answer a plea from their cousin on a New Mexico cattle ranch. They discover how Arrow cigarettes can knock people out using a gas that comes out from a vent in the ground in New Mexico, originally discovered by American Indians.
