Good day, 
I am Li Chin Wu, a Principal assurance Manager for the Huaxia Bank. I am contacting you with regards the estate of one Mr. Peter and an investment placed in our bank 5 years ago. It is important you keep the contents of this mail confidential and respect the integrity of the information you come by as a result of this mail.I contact you independently and no one is informed of this communication.In 2003, the subject matter,Mr.Peter came to our bank to engage in business discussions with our private banking division.He informed us that he had a financial portfolio of 12.4 million United States dollars,which he wished to have us invest on his behalf.
Based on my advice, we invested the money around various opportunities and made attractive margins for our first months of operation, the accrued profit and interest stood at this point at over 14 million United States Dollars. In mid 2005, he instructed that the principal sum (12.4M) be liquidated because he needed to make an urgent investment requiring cash payments in Hong Kong. We got in touch with a specialist bank in Hong Kong the Dah Sing Bank who agreed to receive this money for a fee and make cash available to Mr. Peter . However Dah Sing Bank got in touch with us last year that this money has not been claimed. On further enquiries we found out that Mr. Peter was involved in an accident in Shanghai, which means he died intestate. 
He left no next of kin and the reason I am writing you is because you have the same last name. I have exclusive access to his file, I have the power and know how you will be made the beneficiary of these funds. My bank will contact you informing you that money has been willed to you.On verification, which will be the details I make available to my bank,my bank will instruct Dah Sing Bank to make payments to you. You do not have to have known him. I know this might be a bit heavy for you but please trust me and believe in me on this. For all your involvements and troubles I propose that we split the money in hol?. In the banking circle this happens every time. The other option is that the money be reverted to the state and we get nothing. Nobody is getting hurt, this is a lifetime opportunity for us. I hold the key to these funds, and as a Chinese National we see so much cash and funds being re-assigned daily. I want us to keep communication for now strictly by this email.
Please,note If we can be of one accord, we should act swiftly on this.Please get back to me immediately and provide and reconfirm your full details so we can discuss this matter extensively.
I await your response.
Li Chin Wu.
