The Cove (FBI Thriller 1)

The Cove is a quaint little postcard town made up only of old folk who sell the World's Greatest Ice Cream - a secret recipe that brings lots of tourists into town.
Into The Cove comes Sally Brainerd, daughter of murdered Amory St. John of Washington, D.C., seeking sanctuary, and FBI Special Agent James Quinlan who's undercover and after her. He's got a murder to solve, and he believes she's the key. But is she really?
