Indigo Island and Pinckney Plantation are sweltering under the South Carolina sun as tourists invade in advance of the Fourth of July holiday. But when three cousins who fancy themselves amateur sleuths come upon a long-ago runaway's skeletal remains, the cold case casts a chill on summer fun. Still, it doesn't keep the cousins from planning for a parade and a picnic even as they dig into the island's haunted history while hunting for treasures at an estate sale. Then there's a fire, a suspicious death, and fireworks aplenty as the tables turn. Someone is after the cousins. Is it because they may have discovered a priceless piece of antique jewelry? Or because of what's hidden in the pages of an old diary—a secret to die for? Southern manners again meet mystery as our heroines try to solve the case. Readers everywhere will welcome the return of the detective trio Publishers Weekly calls "a triple treat."
