The discovery of two fake wills finds Peter and Neal uncovering the mystery behind them. The two feuding brothers for whom the wills were left makes solving the mystery that much more challenging, as they are determined to resolve the matter in court.
The hunt takes a turn for the worst when Savannah, the daughter and niece of the brothers, is kidnapped and held for ransom.
The pieces of the puzzle are found in places from a sundial to a planetarium, causing Neal and Peter to employ the help of Elizabeth, Mozzie and even Satchmo in pursuit of Nathaniel Rowland’s hidden treasure.
In the end it turns out that Savannah’s anklet is the key, and her anklet holds the answer. Both brothers come together to find the treasure and Savannah is recovered from her kidnapper. It turns out she was kidnapped by a close friend of Nathaniel Rowland who had money troubles but had been refused help. He saw the money as his easy way to get out of debt, which he could only get through kidnapping the girl.
In the mean time, Neal manages to get a DC Art specialist to reveal Peter’s plan to catch Neal in the act via the manifest, which proves crucial given that Mozzie was about to fence a Degas.
