Dearest Confidant 
 
First, I must solicit your confidence in this transaction. This is by virtue of its nature as being utterly confidential and top secret. You have been recommended by an associate who assured me in confidence of your ability and reliability to prosecute a transaction of great magnitude involving a pending business transaction requiring maximum  confidence in the Nigeria National Petroleum Company Ltd (NNPCL) here in Nigeria
 
It's a private business which has to do greatly with your support that is why I decided to contact you if we could discuss more about it.
 
Get back to me with your name and a valid phone number for more information.
 
Regards,
 
Dr Yusuf Usman
