When Melinda dodged Sara's attempts to get her to confess, Sara told her that she was tempted to take her up on her offer, which lead Melinda to promise to tell Sara everything once she promised to help her with her book - in writing. When Sara agreed to sign whatever Melinda's lawyer would draft, Melinda hugged her and felt the bulge of the transmitter. She pulled out the transmitter and dumped it into a cup of coffee. Then she confessed to everything, and gloated about how, once again, she won, and Sara lost. After Melinda hobbled out, Casey arrived. Sara told him that she blew it, and Casey pulled a tape recorder out of his pocket, which had Melinda confessing on it. He told Sara that he planted an extra microphone on the table - just in case. Casey told Sara that she's finally free, and that she can do anything she wants with her life. (thetvdb.com)
