How to Spend Someone Else's Money

Ever found a fortune or something of great value that is not yours? Lucky you?
If the owner is unknown to you, what do you do?
Nancy finds such an unclaimed fortune and wrestles with the notion of telling someone, or keeping silent.
In this peculiar situation, Nancy knows her husband would not approve of her keeping the money and so keeps him in ignorance whilst she works out what to do with it. Her husband dies never knowing that his wife has a fortune hidden in the house.
Can Nancy find a way of laundering the money and banking it legitimately?
Along the way, Nancy meets a friend who is having a problem with a baby and somehow Nancy feels an inexplicable psychic connection to this child, especially when she realises the child was born on the same day and at the same time that her husband passed away. As the child grows Nancy takes over financing his education and puts him through university and then on to medical school where he becomes a prominent physician.
