Another sweet mystery by Franklin Dixon!

This book, the footprints under the window, is indeed a wonderful mystery ventured by The Hardy boys…

The story starts with a little issue in the Micro-eye factory which turns out to be a great trouble. The Hardy boys set on their journey to find out who are the people behind the problem in the Micro-eye industries…the leak in the project details!
