Sara was mistakenly believed to have been Diana Adams when she was kidnapped from Diana's room and held for ransom.  Sara was covering for her friend Diana A.K.A. Miss Masque while she was on a case to find out what happened to all her friends that have disappeared.  What Diana didn't know was her brother Martin was in love with Sara.  Sara was the daughter of Martin and Diana's,  father's house servants.  Martin's father disapproved of Martin's relationship and would have kept his son from his inheritance.  So, Martin hired two criminals to help him pull off the kidnapping in an attempt to get his inheritance by ransom. They then double crossed Martin and shot him three time killing him.  Sara was not hurt but she was pregnant with Martin's child.  After Martin's death Sara had a son.   Her son had two daughters and the daughters had six more children.
