I read that book and very much liked it :) Manson and his gals were in street clothing and I did not know that was the reason why!
The end of the book mentioned a lot more info on the family where they were, other crimes they were suspected of. Not mentioned in the 1976 movie Helter Skelter (my fav) and it was to say the least, unnerving.
Always love meeting a fellow reader at FR.....
