Curses! (Ghost Detectors, Bk. 10)

When the local museum hosts the exhibit for the mummy of Egyptian king, Tuturtikum, Malcolm and Dandy want to be the first in line. But they soon learn there is more to the mummy than just a wad of rotting rags. They've both become victims of the Tuturtikum curse! It seems the only way to zap the curse is to zap the ghost of Tuturtikum. But can the curse be lifted or will they be jinxed for life?
