The Mystery of the Melted Coins
Suspecting that their friend has been swindled, the Hardy brothers investigate and find themselves on the trail of a much larger criminal operation.

This mystery is a classic of the Hardy Boys - seeing the brothers investigating several different mysteries which come along at the same time - a man with a missing memory, some counterfeit coins, and hidden treasure - but the greatest mystery might be the secret that Aunt Gertrude is keeping.
It contains all the key elements, cliffhangers, captures, Chet - that make the Hardy Boys books a pleasure to read - though a great deal of this is likely nostalgia value from reading them when I was younger.
