Title: Secret Of The Old Mill
Review: I have read many Hardy Boys books. From them The Secret Of The Old Mill is one of the best. The Boys have a case of counterfeiters who are using an old mill as the base of their operations. Meanwhile, their father is involved in an highly confidental case(about which the boys come to know later) of a gang of saboteurs who are trying to sabotage an company named Elekton which lies near the old mill. The boys come to know that both the cases are related.Do read this exciting thrill-packed mystery.
