Dear friend,

My name is Mrs. Mary-Ann Williams, a wife of late Mr. George Williams, an
American Businessman.I got your contact through the listed postal address
in your country. I lost my husband recently to the international disaster
in West Indonesia (the Tsunami attack) and I am also receiving treatment
after the exposure to the hard conditions of the Tsunami. I have been
diagnosed with Esophageal cancer .It has defiled all forms of medical
treatment,and right now I have only about a few months to live, according
to medical experts.

My Late husband and I before is death once asked members of his family to
close one of our accounts and distribute the money which he had there to
charity organization in Ethiopia and Somalia; they refused and kept the
money to themselves. Hence, I do not trust them anymore, as they seem not
to be contended with what my late husband have left for them.

The last of my money, which no one knows of, is secured in a bank in
Europe worth US$15,000,000.00 (Fifteen million United States dollars
only)and secretly defaced and is coded for security reasons; this could be
release in short notice when a willing and acceptable partner emerges.

I will want you to help me collect this deposit and dispatched it to
charity organizations.I have set aside 20% for you and for your time
during this process

Please get back to me with the below information and i will give you more
details.

Name
Address in full
Telephone

I await your immidiate response


Regards,
Mrs Mary Ann Williams.
