On this episode, Megan and RJ take Agatha Christie's sinister choo-choo train to her classic mystery novel, Murder on the Orient Express. Along for the ride is Jess, a high school English teacher and certified Christie-head. We learn that murder is the secret to getting kids to read more, the importance of a well-groomed mustache, and how Christie once pulled a Walter White. Meanwhile, Megan struggles to say a single character name correctly, RJ has some issues with wording, and Jess initiates a blood feud with Kenneth Branagh.
