About
Already in dire financial straits, the Rocky Isle Marine Institute in Maine has lost its prized baby dolphin, and someone's demanding a million-dollar ransom. Nancy suspects that a deadly human shark is on the prowl and she'll take any risk - even act as bait - to ensure the dolphin's return.
