Natural Enemies

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.
