Sandra was your stereotype 1930's woman, a sorta nerd, works as a librarian. She basically was average education woman officially, unofficially she smarter than average, even consider a gifted or genius. What so important about her. Then she good at being a librarian.

About three ago Sandra was arrested for murdering a traveling salesman. The trouble was that she doesn't remember, meeting him, knowing him. But all the evidence says differently.
What's unknown to Sandra, that she is being using by a time traveler from over a hundred years. Why this traveler needs to alter certain events. That he needed to changed to prevent what Sandra great, great, great grandchildren will do something amazing or wonderful.
Again, Sandra was taking over by another person the future. But this one, did wanted to affect her life, but to return her life back to its proper course. This one was her great, great, great grandchild. He wanted her life to returned to what it ordinally was. It took him several months, maybe five or six months, what's so important. To him than returning her to the normal course of events. Well with this time she will meet her future husband. And his future great, great, great grandfather and eventually have children and great, great, great grandchild eventually he'll born and created certain things. He made sure than the ordinally timeline was tract.
After stay extra several weeks to be sure that things are normal for her life that his history is on tract. So he felt that her life on the right path. So he tried to return to his own timeline. Thou he could only return back to his time for only for a few minutes, and then snapped back to Sandra's time. he tried again and again. Thou his time back his time was shorter and shorter. Then he couldn't go back to his time. Then he realized that he is now is great, great, great grandmother. He couldn't return back. So he is now his own great, great, great grandmother. So he or she is Sandra, soon she'll get pregnant and be a mother.
(Paradox theory, what more important the cause, or effect. if you go back in time, will you change history, or will you effect. That is puzzle, some said that traveling into time is creation of history. or did you created a different time event or alternated, would remember it or have a feeling of something.)
