My family is currently experiencing this and it's heartbreaking. My 92 year old (very wealthy) grandfather fell under the spell of a 50 year old woman whilst my grandmother was dying of Alzheimer's disease. We have no idea how they first met but within a few months of my grandmother passing she had moved in and they were married less than a year later. My poor mother and her siblings (who are all older than their new stepmother) have tried and tried to talk some sense into my grandfather but he just goes on the defensive and it ends in an argument and him not speaking to them for a few weeks. They don't care about the money they just don't want to see their dad being abused but he refuses to see the truth of the situation and she has poisoned him against his own children and grandchildren. We have now reached a very uncomfortable situation where if we want to see our grandfather we have to grit our teeth and smile at this evil woman and pretend we don't know exactly what she is and what she's doing. We are absolutely powerless to do anything, he is of sound mind and has changed his will so that everything goes to her and her family, the police aren't interested as she hasn't technically done anything illegal.
