The Soul of Genius

The Soul of Genius is the twenty-first episode of Lewis, taken from series six. It first aired on 16 May 2012.

Synopsis
A botanist accidentally unearths the corpse of a recently buried professor who was fixated upon solving a seemingly impossible riddle by Lewis Carroll. The victim had a long-standing rivalry with his brother – giving Lewis and Hathaway an obvious suspect – but the case is hindered by the mind games of two students who seem intent on causing trouble in their quest to gain admittance to a mysterious club.
