Entry Wounds, Pt. 2

S8, E102: Crime drama series. A lack of experienced officers means that Chief Superintendent Innocent has asked Lewis to come out of retirement to help newly promoted DI Hathaway with his first murder investigation. Neurosurgeon Alastair Stoke was shot in the head on the farmland he co-owned with his troubled business partner, but as Hathaway delves into the network of fear and loathing that surrounds the surgeon, the case begins to career out of control. With the prime suspect murdered by a weapon supposedly in the police's possession, Hathaway's theory has fallen apart. It might take Lewis's insight to close the case - but will his former protege listen?
