T12:C03 - S12:E03 - Secrets and Spies

Former secret agent Geoffrey Larkin arrives in Midsomer Parva and stays at Allenby House, a country mansion run by former spies Sir Malcolm Frazer (Benjamin Whitrow), his son Nicky (Peter Davison) and Nicky's wife Jenny (Alice Krige) as a safe house. Geoffrey is soon gashed to death after a cricket match in Midsomer Parva, and the locals blame the 'beast of Midsomer'. However, Barnaby - a former spy himself - soon realises that the killing has links to Allenby House and Cold War Berlin, but is initially thrown off the case by MI6. But when a further murder occurs MI6 Agent Glen Jarvis (Neil Stuke) asks Barnaby back on the case.
