Help me and my sister now. My name is Joshua.we are the children of late Mr.Amos.Our late father was a very rich man before his death.Our father and mother is dead now.I am 21 years old and my sister is 19 years old.I arrived with my sister here, in Accra,republic of Ghana last week.We escape from freetown,republic of Sierra Leone because our Uncle wanted to poison us so as to inherit all my late father's wealth and estates.Even now,our Uncle have collected all my father's properties like buildings,factory,cars,e.t.c. Our Uncle and his wife always punish me and my sister.The wife of my Uncle served me a poisoned rice meal, but God saved me and my sister.we did not to eat the rice meal.I threw away the rice meal into the dust bin and on the following morning,i discovered and found the house cat dead in the dust bin after eating the poisoned rice.God saved my life from my wicked uncle.That was why i ran away with my sister from our home in Freetown immediately to Accra,republic of Ghana.We are now save in a hotel in Accra,Ghana. Before the death of our father in a private hospital in Freetown,he secretly called me by his hospital bed side and told me that he deposited USD $20 million for Me and my sister.Me and my sister need you to help us keep the USD $20 million dollars secure with business investment in your country.This is because me and my sister is too young to manage and keep this big cash by ourselves.we wish to continue our education in your country and you will help us invest the money in your country.Me and sister agreed to reward you with $2 Million out of the $20 Million if you will help us. Our Uncle would have stolen our $20 million if our Uncle had known about the $20 million,but thank God me and my sister kept the secret and never allow our wicked uncle and his wife to know about our $20 million that is save here in Accra,Ghana.So ,please never let anybody to know about our $20 million.It is only me,my sister and you that know the secret now about our $20 million dollars. So ,please never let anybody to know about our $20 million. Me and my sister wish that you will be sincere and honest to us,because the $2 Million we have promise you is good enough to make you to be kind and love orphans like me and my sister.We wish that you will love and take care of us because we have no father and mother. My sister and myself want to study our education in your country.A good medical university in your country. Because i will study medicine so that i will become a medical doctor.My sister will study nurse so that she will become a professional nurse.We have good plans to build a very big hospital in your country after my sister and myself graduate from the medical university. Explain very well to me the kind of company business investment that is very good and profitable in your country.Is it oil business that is good ? Or is it stock exchange market that is good in your country ? or is it your own company business that is good ? Which business do your company invest ? Explain everything well for me now.
