Query: A story half-written.

Bravin has chosen to write a biography of a woman who usually appears as a side character to Charles Manson. What begins promisingly, though,soon turns into another biography on Manson himself, and the realm of information he uncovers about her pre-Charlie life suddenly stops, and we are told little then that we didn't know from "Helter Skelter". Unfortunately, fascinating theories about her father are unresolved, and because Fromme wouldn't talk herself, there are no clues to the woman's mind after 20-plus years in prison.
