It was tradition for most of the residents of Grosvenor, NJ, to come into the town center for celebrations, eating, enjoying the festivities, and watching the annual Fourth of July fireworks. Except this year it was different. Greedy developer Keith Hollis decided to go up to the quarry for unknown reasons. It's at the bottom of that quarry that his lifeless body is discovered, throwing the people of Grosvenor into a state of shock.
Many people have been strongly opposed to Hollis's plan to pave paradise and build McMansions over the old quarry and are immediately on Detective Davis and Brady's suspect list. But Hollis is universally disliked, making the list of suspects impossibly long.
However, nursery school teacher and amateur detective, Wally Morris, has questions and ideas of her own. She's solved other mysteries in the town, mysteries that stumped the police. She's always had success but this time she might find herself in a real cliffhanger.
