The seaside town of Peachtree Point, New Hampshire is preparing for the annual peach festival. The town librarians, Heather and Sylvie, are readying the library for several events when Heather notices Sylvie isn’t her usual self. Her boyfriend, Frank, a high school teacher, and another teacher at the school have been asked to write a play on the history of Peachtree Point, but working together leads to trouble. Sylvie and Frank’s relationship is in jeopardy, there’s a new detective in town, and someone is murdered during the festival. Will Heather and Sylvie along with Booker the cat, their family and friends, and the library’s murder posse get to the bottom of the crime before the whole town learns that murder is the pits?
