White Oleander
Ingrid is a poet who falls in love with a man named Barry Kolker.  However he is not loyal to her and sees other women.  Ingrid kills him by going to Mexico and buying a drug.  She then smears it over all of the surfaces.  Barry touches these surfaces, the poison gets in his body, and he dies.  She goes to jail and is later found guilty for killing him and goes to prison for a long time.  Her daughter, Astrid, is taken to a series of foster homes.
