Will (Tom Brittney, below) and Geordie might have met their match this week when a murder takes place at an old folks’ home and two of the residents (gueststars Bruce Alexander and Anna Calder-Marshall) go missing. Are the duo involved in the crime, or are they just giving the detectives the run-around? Meanwhile, Geordie and Kathy are further apart than ever when she joins a protest. ★★★☆☆
