A few weeks ago, Liz Jennings found out that her grandfather had recently died. She had never met him, so she went to the small Texas town of Brockmeyer. A popular Austin radio show host named Seamus "Shame" Fuller comes to see Liz soon after she arrives. Shame tells Liz that he thinks her grandfather may have been involved in the assassination of President John F. Kennedy, but he doesn't know for sure. Liz isn't sure at first, but she soon agrees to help Shame find the answers he needs.
