Another perfect summer is in full swing on Martha’s Vineyard when Charles Williams arrives for the vacation of a lifetime. Charles is one of thousands who are there for the celebration of the 1975 blockbuster JAWS. Very little has changed since it was shot there almost forty years ago; however, Martha’s Vineyard proves to be less than idyllic. The gruesome evidence of a fatal shark attack is discovered in the ocean while in Edgartown, vacationers fall victim to an unknown killer. Police Chief Laurie Knickles enlists the help of her friend and amateur sleuth, Charles Williams, as they suspect no one will be safe in the water or on land until they solve The JAWSfest Murders.
