Didion also discisses several prison meetings with Linda Kasabian, who at the time was testifying against Manson, Krenwinkel, Atkins and Van Houten for the TLB murders. Apparently, Sharon had been an acquaintance of Didion's. The murder trial cast a cloud of fear over Hollywood that seemed to propel many of Didion's insights. The impression conveyed is one of a city and nation pervaded by paranoia and detachment.
