Why should we believe that what you've written above is truthful? How do we know what you said wasn't the result of extortion, threats, a bribe, or a promise of future goodies for retracting the first story. Claiming you were conned is a very small price to pay and from the comments, looks like it has increased your standing.
But, who is the guy? He had maintained a positive and useful cover for 20 years. You used him before but never had to contact him to check a fact or ask for a lead? And, why/how would he have identified you 20 years ago as a person he could con 20 years hence? Has any money, either way, ever changed hands? And, if you, why not several of your coequals?
I'm sorry, the story is too neat, too glib. There is more to it than has been written here.
I'm not buying it..
Yes, and why are your other contacts who you claim knew him not being identified?
