By Vincent Bugliosi with Curt Gentry. Funny thing about Helter Skelter -- I almost never get used copies I can sell. Dog-eared all to hell, covers coming off...people really read it hard, this book. This one isn't perfect, but it's better than most, and it's the other classic-look Bantam (this one appears to be a 40th (!) printing from the early '80s).
There's the wear you'd expect to this PB: a couple of cover creases, edgewear, a faint crack to the spine, page toning -- but it sits very straight, and if you can live with some "vintage visuals," this is a nice price.
