This was a very disappointing book. As a skeptic, all I could do was wonder at the tenacity of the journalists who were trying to find "Maria Duval", a legendary psychic who's name was used all over a large number of direct mail campaigns to suckers (old people and such) to elicit funds from them for "blessings" and stuff. Apparently, their research resulted in a CNN expose in 2016.
This is a serious issue, of course. My mother got taken for a few dollars simply because her memory was dodgy. We were lucky and stopped it early. One anecdote in the book speaks of an elderly woman who mailed her "application" in with her credit card paper-clipped to it. She attached a note to the effect of "Please: you fill it out and send me back the card".
They found Maria Duval, a little old lady who had sold her name off years ago and was now, for the most part, a typical victim of the scams she started, rather than the perp.
News flash: Scammers are adept at hiding their tracks, and there is a world-wide market place for "sucker lists" that they use to bleed the vulnerable dry. Knock me over with a feather!
The only good thing I can say about this book is that it is a fast read. No index. Few notes.
