Tricia Miles, owner of the Haven't Got a Clue mystery bookstore in Stoneham, New Hampshire, can't walk away from a good mystery. Her sister Angelica, who sees herself as the next celebrity chef, is hosting a launch party for her first cookbook when a nearby gas explosion injures her boyfriend, Bob Kelly. When Tricia reads that Bob is being tight-lipped about the accident, and how it killed the owner of the town's history bookstore, it's time to take action.
