looking for story about a rich widower who is estranged from his son and daughter. one day he hires a high class social escort for an event and it turns out to be his daughter but she's changed her identity and had the records sealed/destroyed. I vaguely recalled that she had long black hair and she wore a silver backless dress to the event
they end up falling in love and getting married
another detail i remember is that her name is/was samantha
