Natural Enemies
When Ned's invited to study at the Rocky Isle Marine Institute in Maine, Nancy joins him as a volunteer at the facility's aquarium. But Ned fears that a handsome tour guide is creating serious waves in their relationship. Nancy, however, has to deal with a different kind of storm -- one threatening to destroy the entire institute. Already in dire financial straits, the aquarium has lost its prized baby dolphin, and someone's demanding a million-dollar ransom. Is it Matt FaIton, animal-rights activist and major TV star? Nancy suspects that a deadlier human shark is on the prowl, and she'll take any risk -- even act as bait -- to ensure the dolphin's safe return!
