I would stay away from reading any of this man's work! In Australia he is infamous, Andrew Fitzherbert was convicted of the murder of Dr Kathleen Marshall, an Australian veterinarian in 1998. She was stabbed by him more than 50 times! He served 15 years in prison!
'Andrew Fitzherbert, palm reader from Zillmere and the founder of the Queensland Palmistry Guild, was prosecuted and convicted for her murder based on DNA evidence.'
He may claim to be innocent but he was convicted and sentenced in the court of law. He received a fair trial, so his claims are useless!!
I would not touch this man's work with a barge pole, or give any of it any credibility.
I state categorically that this is only my opinion, read his works by all means but read them with a grain of salt and be aware of his history before accepting the words of such an individual.
