The Hidden Harbor Mystery

Blurb

The Hidden Harbor Mystery is Volume 14 in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap.
This book was written for the Stratemeyer Syndicate in 1935, purportedly by Leslie McFarlane; however, the writing style is noticeably different from other books in the series known to have been written by McFarlane. 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 1961 by James Beuchler resulting in two different stories with the same title.
The original story contained racial stereotypes which were removed during the revision. For example, the chief villain, a young Black man named Luke Jones is described in the 1935 edition as "the worst scoundrel we have ever come across", but is completely removed from the 1961 version, and most characters identifiable as Black have been reworked as racially ambiguous.
