Footprints Under the Window is Volume 12 in the original The Hardy Boys Mystery Stories published by Grosset & Dunlap.
This book was written for the Stratemeyer Syndicate in 1933, 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 1965 by David Grambs, resulting in two different stories with the same title.

Plot summary (revised edition)
Frank and Joe attempt to uncover a plot to smuggle refugees from Baredo in the Huellas (a fictional island nation off the coast of French Guiana) into the United States, and the involvement of local magnate Orrin North. They also get involved with investigating attempts to spy on a top-secret satellite camera being built at a local company called Micro-Eye. Someone has managed to infiltrate security at the plant and has taken photos of blueprints.
Realizing that several clues point to the involvement of people from Baredo, Frank and Joe and their friend Chet Morton fly down to Cayenne, French Guiana, and then Baredo in the nearby Huellas to investigate. What they discover is that Orrin North, while supposedly on the side of rebels against the dictator of Baredo, is actually double-crossing the rebels by finding out their identities and capturing them.
Returning to Bayport, the boys overhear a plot to steal the satellite camera the very next day, but they are captured and taken aboard a ship where they are locked into a hold being filled with water. They manage to escape from the hold with the assistance of their father, Fenton Hardy, who has been on the same case and went after this ship at the same time. They free the political prisoners on board and capture the criminals with the assistance of the Coast Guard.
