Diana: Death of a Goddess received mixed reviews.
Beryl Bainbridge writing for
New Statesman called it a "good read" that "goes a long way towards raising doubts" about the official ruling of the case. She said the book "uncovers much that was deliberately concealed", and praised it for being informational without becoming sensational, saying the book gave a "riveting" account of Henri Paul's life.
The Sunday Age said that though many of Cohen's conclusions seemed credible, the Solar Temple link required "a stretch of the imagination". Manning noted the connection as "a strand in the conspiracy web that hasn't been examined before".
Jean-François Mayer, a researcher of the Solar Temple, cited the book as one of many works promoting "far-fetched rumors linking the Solar Temple to all kinds of criminal cases and other mysterious events", with Cohen speaking to dubious figures in his investigation on the group. He said that there was no trace of any such tie substantiated by the investigation into the OTS. The claim of the connection to Grace Kelly likely stems from the fact that Jean-Louis Marsan, the Grand Master of the
Sovereign Order of the Solar Temple (OSTS), was a childhood friend of
Rainier III, Prince of Monaco, Kelly's husband. Despite the name, the OSTS was a different neo-Templar order and had little to no connection to the Solar Temple, though Marsan had met its leader on one occasion. == References ==
