Q: This book truly lives up to what Vincent Bugliosi says on the first page of his book "Helter Skelter-The True Story Of The Manson Murders"-- "This story you are about to read will scare the hell out of you." This is not only the best true crime book ever written, but it is the ONLY true crime story ever written. Mr. Bugliosi is truly a judicial genius, and should be highly commended not only for putting Charles Manson, Susuan Atkins, Patricia Krenwinkel, Leslie Van Houten, and Charles Watson behind bars forever so they can never harm another living soul again, but for writing this fantastic but bone-chilling book.
A:
Positive
