Negative

All of the good things said about "Helter Skelter" is true of the Kindle edition. What's more the Kindle edition has hyperlinked footnotes that actually work and take you instantly to Bugliosi's notes. But the trade-off is that with the Kindle edition THERE ARE NO PICTURES because of licensing issues. The print edition has lots of pictures, but many of the crime-scene photo's are censored.
Positive

Utterly amazing and unique sound. Her voice is so powerful.
