In a fourth outing, Emma Chizzit, the busybody owner of A-1 Salvage, and her best friend Frannie (Emma Chizzit and the Napa Nemesis, etc.), on a visit to Buckeye, California, quickly bump into two factions with different ideas on how to exploit the old mining site: pretty, aggressive Trooper Hadley, a tour promoter, wants to add it to her expensive tour excursions, and a group of town nabobs wants to level the old gold rush remains and erect a massive shopping mall. Jimmy Simpson, a young reporter chum of Emma's, suspects trouble and is proved right when rattlers are placed in picnic hampers, an old-timer's barn housing gold-mining artifacts is torched, and nasty ``Don't Tread on Me'' notes are found. When Trooper's car careens off the mountain, Jimmy, heir to her Buckeye Foundation, and Emma are determined to foil the real- estate scheme.... Not much mystery and even less characterization. Some interesting gold-mining detail, but, mostly, silly dialogue occurring in improbable situations.
