When Frannie's dad transferred to Oregon, all she worried about was going to a new school, and why she and her twin, Jeff, weren't close. Frannie also dreamed about her missing Mom, and why she had never returned. Ghosts, a long ago murder, and helping to trap a killer was not on her "worry" list. Yet a late night visit from a scary apparition, trailing long gray veils and begging for Frannie's help, changed everything. Twin Jeff and her dad thought ghosts were rubbish. So Frannie and the ghost, who was amazingly kind and friendly, put their heads together and planned Revenge. A chilling encounter in the basement, and the appearance of the ghost's familiar, an arachnid of gargantuan size, persuaded Jeff to help them trap Thelma Hill's killer. The panicked and treacherous killer pays a midnight visit. After the hoo-hah dies down, Dad meets a reporter he can't say no to, and Thelma Hill returns with news of Frannie's mom.
