Treasure both ancient and hidden as Ria seeks to find the secrets held in a prehistoric stone chamber and to outwit an intruder who sees the Fourth of July as a cover for murder... "It's the Fourth of July in Shokan Falls, grand cause for a jubilant celebration with bunting and streamers and flags, picnics in the park, a Ferris wheel, and a brass band playing in the gazebo. Yet once more, Ria finds herself in the middle of a deadly puzzle. Near dawn, before the festive day begins, she goes with the Benedictine monk Brother Jocelin to explore a sacred prehistoric stone chamber, long hidden in the nearby woods. As the rising sun enters the opening to it, they find a body lying under a shroud on a high bier. Not long after, when the celebration is in full swing, another suspicious death occurs, this time in the park. Searching for answers, Ria discovers quartz gold deposits were once mined in the area, knowledge that sends her into danger. But it is when she is at Deidre's for an evening of psychic readings that the mysterious power within the ancient stone chamber is suddenly revealed to her. And the identity of a killer."
