International scam for the day

Rico says it's the old Gaddafi scam again:

From: James Mambo

Good day. 

I am contacting you with a good faith and believing that you are going to assist me in this transaction. Do not see this email as one of the scam mails. For your assistance in this transaction, this $85 million dollars this fund belonged to my late client, Muammar al-Gaddafi, former president of Libya.
As, after his death, all of his family members was arrested, I have shifted the funds to an escrow account so that nobody will have access to the funds again. I want to invest the fund in your country. All I want from you is your honesty and sincerity for you to tell me that you are not going to expose the fund and both of us will sign agreement which I will give you thirty percent for your assistance in this transaction. Please kindly get back to me and let me know the line of business where we can invest this money in your country. Send me your full name, address, and phone number at this email.

Best regards 

Mr. James Mambo
