This book was written for the Stratemeyer Syndicate by Charles S. Strong and rewritten by Harriet Adams.

[1] The original version of this book was shortened in 1971 by Priscilla Baker-Carr[2] resulting in two slightly different stories sharing the same title.

The Hardy Boys solve a kidnapping and break up a gang smuggling illegal aliens from India who are also holding an Indian prince captive.

An official of the Indian government saw to it that a trained peregrine falcon was delivered to the boys to use in their investigation.

Finally, the boys rescue the Indian prince and catch the human smugglers along with creating a strong bond between India and the Hardys.
