The Secret of the Old Mill
Counterfeit bills are turning up all over Bayport, and after Frank and Joe get stuck with a fake note themselves, the Hardy Boys decide to trace the phony money to its source. The third book in the series points them toward a renovated mill on the outskirts of town and a tight-lipped operator who does not welcome visitors. Threats against their family only sharpen the brothers’ resolve. Between hidden machinery and coded deliveries, the case builds to a genuinely tense finish. First published in 1927 under the collective Franklin W. Dixon byline, it is a clean, well-plotted example of what made the early series stick with young readers.
