I am more inclined to think that perhaps AH met this Blum in the early 2010s in Bali - it was around this time he was using Bali as a destination point to entice his victims.
The book launch was 2019 - the author could have sat on the draft for yrs and AH may have 'helped' himself to the ideas for a new scam IF they knew each other while AH frequented Bali?
His daughter was married there 2011
AH changed his name to Blum in 2014
It would be another way to blow his scent attaching it to a person who wrote a book about the very things AH used for his scams.
He uses the work of others to interweave his own traps - we have seen it many times that he uses books to gather his information. He is a lazy SOB - he wouldnt be writing a book about his crimes!
He is a bigger star than that in his own mind - he is wanting FAME and recognition. In his own sick and twisted mind he would know that one day he will be written about, there will be a movie about him and he will be infamous showing the world how lax the Governing departments are in the world and how stupid women are in his mind.
He is a narcissist, the worst of them and he wants the fame.
Writing one miserable book as thin as his pinkie wont give him recognition.
He or Dianne possibly knew this man and he took what he wanted from him.
All the names of his aliases so far have been linked to real people. This could really be why he used the name Blum
Blum - Bali - preying on women - a little book draft he came across when he met someone
Just like the NY book and the red cedar plantation he BS about.
I found a photo of Chacko and another man holding the book

I would have a guess and say this is the author of the book
