Just as I completed the Nancy Drew series, I just remembered of its counterpart- The Hardy Boys!

Franklin Dixon has indeed written a wonderful mystery series!

Frank and Joe start with a pleasant day enjoying it with their friend Chet, moving through the streets in The Queen. But as their days went, 20 dollar counterfeit bills started to pass across the place. This aroused a mystery for the Hardy Boys to break!

As they moved on investigating about the counterfiet, they got another big surprise- their father had also been assigned a case but it was a confidential one. There seemed to be no problem until they got a doubt- What if the case that Mr.Hardy is dealing with the same as theirs?

As investigations move further, they find a great link between the two cases that is being dealed with. And the Old mill serves as the link. But how?

As the Hardy boys continue their sleuth, they were approaching the end of the mystery. The secret behind the cases were to be revealed…the secret of the old mill was to be revealed…

But the only problem was how??

Dangers keep meeting them as the Hardy boys work on finding out the secret…

The secret of the old mill!
