During the investigation at the library where Vera used to work, they run into Karen and Diver, who confess about a letter Kent sent them. Hoping to get additional clues, they are shocked when they uncover a huge surprise on a bookshelf. Later, Dianne points out Jack, and the killer might not be so different after all.
