Another chance to see this excellent episode entitled Old, Unhappy, Far Off Things, first shown back in 2011 and guest-starring Juliet Stevenson and Saskia Reeves.

Lewis and Hathaway are back on the job, investigating a murder at a college reunion – and Lewis is even more determined to catch the culprit when he spots connections to an unsolved case from 10 years ago.

But when Hobson reveals that Lewis was working at the same college when his wife died, Hathaway worries that his personal life might be interfering with his policing.

Once again the pair’s banter and the stunning Oxford backdrop make this crime drama stand head and shoulders above the rest.
