Prashan Rodrigo?? "The Jew who came from Nowhere" or "Diminishing Sri Lankan Royal Jews",

In 2009 I posted an item on Prashan Rodrigo who had self published a book on Jews in Sri Lanka. The books title is "The Jew who came from Nowhere" or  "Diminishing Sri Lankan Royal Jews",

I have had no responses for more information about the book or how to contact Mr Rodrigo. I do not have a copy of the book. So I am making a new appeal - if you have any further information, no matter how small - please contact me.
