Just as suspected, Mr. Basswood is taking more money from Mrs.Merriam's book sales.
The statue can go back to it's original spot at the yacht club. I can see that it is in good hands.
Nancy was hired at Mr. Basswood's art shop and did some sleuthing while she was there. Her investigations lead her to the fact that all of her suspicions about Mr. Basswood were correct.
In the end, Nancy found the real Whispering Statue and the owner, Mrs. King, was happy to give it to the yacht club. Also Mr. Basswood and Mr. Atkin were both taken into police custody. As were everyone else who was involved in the case.
