into Mars Investigations, trying to find the bug, and Tim effectively enlists Veronica's help. They visit the convenience store with no luck for the time being. Wallace (Percy Daggs III) sees Logan (Jason Dohring) and Parker (Julie Gonzalo) having lunch together and tells Veronica, but she doesn't seem upset. Mindy buys a boat at the local pier. Keith and Veronica receive news that Mindy has left town. Veronica and Tim investigate Hank's alibi further, and it checks out, leading to his release. Veronica and Tim find secret phone recordings kept by Hank. Veronica brings Keith the CD, but he informs her that Hank has disappeared as well. We see Hank showing up on Mindy's boat. While listening to the phone calls, Veronica notices Mindy and Hank talking about a place named "Papa's cabin". They investigate the most recent phone calls made by Hank, and find that his alibi was faked—he was helping the witness's son escape foster care. Keith comes up with the idea that Papa's cabin has something to do with Ernest Hemingway. Keith visits the cabin, a retreat in Mexico, before boarding the motorboat. He finds Hank, who says that he was working with her to kill the Dean. He says that he and Mindy had a fight, and Mindy fell overboard. We see Mindy's body washed up on a beach. With Landry arrested, Tim takes over the criminology class. The class starts to discuss the Dean O'Dell case, with Tim giving a broad overview of the subject. However, Veronica asks several questions to him which he does not answer very well. Veronica suddenly connects the dots and says that Tim committed the murder in order to frame Hank, who denied him a job opportunity. Tim is arrested and confesses to the murder, while Hank is being tried for manslaughter in the death of Mindy. Keith and Veronica share dinner after solving their cases.
